I believe a selling point of the g250 was the bigger exhaust valve. Don't think the 156 ever was changed...
 
Thanks couv, I sent a message about the for sale listing last night, it is over a year old but figured I would give it a shot. But if I am mistaken about the exhaust vale sizes, then my interest is lost. I have a box full of MK10 and MK5, so I am good on that.
 
The later model BA/156 have the same size exhaust as the G250

@rhwestfall ....back to the cold shower for you Bob.

And that one being a later model! If I was a gambling man I would probably take a punt on that 156 having the larger exhaust.

@reefrat You would make a good gambler. Yes, it's a later model BA with the G250 sized exhaust valve. However, I like the 109 knurled adjustment knobs so it's sporting one of those.
 
It's times like these that I wish for a complete Scubapro catalog collection for reference while looking for specific features and changes over the years. I have the VDH collection plus a few recent ones, but nothing in between.

I am jealous of the BA featured in your photo couv, am I correctly seeing that is has the satin finish? I am tempted to pick up a satin finish BA or two when the right price comes around and try my luck, at least they hold value well so not much to lose.

@Kupu Yes, it has a satin finish; I guess I should have done a better job at photographing it. Note that not all BAs with a satin finish have the large exhaust valve.

I'll keep you in mind when/if I let go of any.
 
I am using one. Love the classic look and it moisturizes air fine. Smoother-breathing than my G250. The first stage Mk10 also seems undestructible. The satin chrome is appealing. The MARK X Dual-Balanced version was mainly bought up by Germans in the 80s. They have them ocassionally on sale in a pretty good shape usually for a lot better price than rebuilt BAs in the U.S... All moving parts inside are G250-interchangeable. Easy to service. The diaphragm is still available in a transparent version. My only concerns are the black rubber diaphragm covers (can crack if dried), and the exhaust tees. Dunno where to get spare ones... so I am taking care of the originals by not letting them dry out. I dare not use the seat-saver key for fear of distorting the rubber cover. Easier to change seats yearly... It seems to breathe even nicer with the new, double O-ringed S-wing poppet...

Necro thread. Silicone parts including the covers and tees were available in the US from VDH. But that source has passed on :(. I stocked up a few of both for my small fleet.

The diaphragm cover I've 3d printed in TPU with success... not as pretty as silicone, but functional:
I've cast a usable T in silicone out of 3d printed molds, but it's still a work in progress.
