liability risk, better off scrapping and writing them off. even then, the ownership stamping is also X'd out as part of the scrapping.

chances are good there is a LS stamped somewhere else on the neck denoting it was a leased cylinder that didn't get turned back in.
 
Does BOC not sell off cylinders to private individuals?
Nope LOL

In the UK they all BOC, Air Products, Linde, Air Liquide have a department that specialises in cylinder recovery.
It's pretty common for brazing workshops garages hospitals, vets and the like in the UK to loose cylinders. The responsible party with the original hire agreement is still charged rental until the loss is known and or declared then they are charged an additional lost cylinder fee.

The valve stem outlet is modified by removing the spring and poppet one way valve that stops users refilling the bottle and the plastic collar is also removed that contains the ID chip. All the gas companies take theft of their cylinders pretty seriously and are know to prosecute whoever is left last holding the can so to speak.
The valve in question in the photo will be made by a company called Muller if the OP would be so kind as to take another photo of the cylinder valve from the right. The cylinder was made by a company called CTCO it must be around 30 years old maybe more guessing from the photo. All details needed by the original owners will be stamped on the neck and are used by the original owners and claimants by which to ascertain ownership.

Again this is why I asked the OP if he had the documentation for the cylinders. Unlike scuba cylinders industrial cylinders purchased from new are provided with all the correct traveller documents. GA drawing test cert, metal certification etc.

Not a bad idea, Truth is it's the original owner BOC etc that get the liability claims should these untested stolen cylinders go bang in the night so to speak as they are still the rightful owners of the property and they are liable unless spending money defending themselves that the cylinder in question should it cause damage was stolen. Hence why they have such a determined recovery section.

Now who was it who posted all that advise about taking the test house up with the small claims court. Ah that would be Edward our very own BSAC advanced instructor trainer.......about to cook himself up some crow pie I guess.

Huh. Interesting. I’ve bought a number of cylinders from Airgas (an American gas house, like Air Liquide or Linde) stamped with their markings, they maintain my records at the shop, I can trade in and not incur retesting fees as long as I don’t turn it in out of test (all of my ABO, CO2 and Argon are expired). But I don’t pay rental on them.

Same. I own 50 or so bulk cylinders for oxygen and helium. The local gas houses swap them as owned cylinders. At this point, there are not specific cylinders that I own, just quantity and size. The ones I get back have varying test dates and neck stampings. When I take them back for fills, they swap another cylinder and I own that one now.

At one time in my life I owned 50 helium cylinders and 100 ABO O2 cylinders.

I've since pared down.

This would be a great time to own 50 helium cylinders. I have swapped many of my oxygen cylinders to helium as prices are so random on helium these days. Oxygen has gone up, but it hasn't been volatile. I don't feel like I need to keep as much on hand.

I bought them at 95 for UHP including the cylinder and sold at $500.

all good.
 
O you again,you not found someone else to pull to pieces ,guess not o lucky me so not only are you trolling me on this site you’re searching for me on the net to (bit of a concern) but why am I not surprised by this,the cylinder you’re displaying here has bin used as bank cylinder for many years long before I bought it,looking at all the stamps on it going back to the early 50s now I can read most of the stamping after blasting, it is indeed a very old boc cylinder i still didn’t notice after blasting and painting but thanks to you investigating and your magnifying glass you have spotted it congratulations give that ego of yours a good pat, something tells me boc will have no interest in this cylinder giving how long ago it’s come out of main stream service, probably before I was born, I’m sure you will be reporting it to boc and grabbing your keyboard to correct me no doubt.

But getting back to the point of this post before you high jacked it being a smart ar#e, that one cylinder is a low pressure odd ball of the bunch that needed testing or scrapping that I’m not keeping anyway, it’s the other cylinders that are in question and the tactics of the test place to push up the price that I’m questioning, when I phoned the test place I answered all the questions about the cylinders I was asked size pressure etc I didn’t know if the bottom of the cylinder is round and not flat it was a completely different testing process etc I thought a hydro test was a hydro test but you live and learn I guess, I was quoted £400 total , but my suspicions began after unloading the cylinders on his stacker truck, he was letting that cylinder in the picture roll off his forks and drop about 3ft into a holding frame, (if any valves are bent now I’ll know why) same with the rest of the cylinders, but the pictured cylinder has the upper part of the valve made off centre to the threaded portion that screws into the cylinder so when it was rolling off his fork lift forks it looked bent but it was just the upper portion of the valve is made off centre, he then tells me they will all need new valves at extra cost I asked why do they need valves he told me their bent I pointed out that the upper portion is manufactured off centre that’s why it looks bent when he was sat on his stacker truck watching it roll off his forks, but he just dismissed what I was saying and told me he will cut the threads and give it me back after test, then he started on about the round bottom cylinders.

At that point I should of insisted he put them back on the trailer and taken them somewhere else but no doubt he would of watched me struggle to get them back on the trailer on my own, after waiting several weeks I phoned up to see how things was going but I was told they haven’t bin looked at yet, a couple of days after I get a call from someone else from the place saying they all need new valves because they don’t test valves and one cylinder has failed but couldn’t tell me on what, corrosion he thinks, i said I was planning on stripping and ultrasonic cleaning them and fitting new seals etc myself and that’s how we left it, then I get a call the next day saying 5 valves have failed test(so you test valves now🤔) on the threads, so I told them before dropping them off I had the valves out and the threads was spot on no damage,he dismissed what I said then tells me that the valves makes a bur on the thread when screwed in and when unscrewed it damages the thread, when I removed the valves to inspect the internals I didn’t see the point of resealing the valves i just screwed them back by hand and gently nipped them up, so I said no problem I’d like to see these valves with damaged threads and in the conversation he didnt notice but he started saying 4 valves have failed instead of 5 that he was saying earlier, it just carried on from their, telling me I can’t see any old valves or cylinders as they have bin scrapped and the all in price including vat that I was given at the beginning had the extra cost of the round base cylinders and the 4 valves added to it and vat added to the total again, at this point I’m pulling my hair out with this place, then I’m told I’ve got to pay upfront before i can collect.
Sounds like a commercial test house that needs avoiding.

You could go down the legal route, but we have only heard one side of the event. Unless it’s particularly important to you, just write it down to experience and move on.
