Help required to identify 3x 1st stage regs

[Reptile_Smile]

Hi all,

Thanks in advance for any help or thoughts. I'm trying to identify any or all of these 3 first stage regs. I imagine they're all quite old, and would therefore appreciate knowing whether service kits arestill available for any of them, or whether they're basically paper weighrts.

Thanks

The first set of pictures belong to an Oceanic DX4, the second set to an Oceanic Balanced flow through piston (pre 1995) and the last set appears to be an Apeks T20.
If you can find spare parts for these I can't say, but you may get lucky at least on the Apeks. As far as I can tell it shares the same parts as their US4, which has service kits readily available. The Oceanics are more than 20 years old and Oceanic does not have a stellar track record on supporting older equipment. I'd be delighted to be wrong on this though!

With the attached you should be able to google for parts or ask suppliers directly if they sell you service kits.

Now here is one important bit, do not tell @happy-diver that I told you this, he is already grumpy enough with me!

Having looked at the T20 service manual (invaluable), I noticed it covers several variants, one of which seems to have the right number of ports, because that's the thing that's baffled me about it - it only has one LP port, and one HP port.

I think that might mean it's an Apeks US1. Does this sound plausible? To add to the evidence, it came as part of a job lot that included a pony bottle, and I presume it was probably the reg for that?

While I don't know any overseas resources, here in the US, Northeast Scuba supply had aftermarket service kits made up for almost all of the old pre-Huish Oceanic products. He sells them to anybody that needs them.
John is a great resource on the old Oceanic stuff.

do not tell

Tanks A Lot your ability to select from a vast collection of files is to be admired or maybe it's the files
