Identifying older us diver regulators

[Seasaw]

I have obtained several us divers second stages. I'm guessing they are about 10 years old basic models. Both are all plastic with no external adjustments (similar to conshelf) but have no identifying "stickers" on the purge button. Can anyone suggest a referrence source to try and identify the specific models? Any help most welcome.

Yeah, post a pic or two or three here, and I bet someone here will know what they are...

Hi,
Here is a picture of the two second stages, much easier to see if you double click them, again, any help welcome!
Thanks!

i´m not sure but i think the reg at left side is a aquarius model which comes with a piston non balance first stage ( similar to SP mk2) that gives its name..the other is very likely older...

I think that the one on the left is a Conshelf, and the one on the right is the Aquarius...

However, I might be wrong, and they BOTH could be Conshelfs from different years...

I'm certain of Conshelf 22 (right) & Aquarius (left). Should be identical except for the case cover.

Hi Guys,
Thanks for all the feedback on the regs. An lds service guy told me he's pretty sure the one on the left is a "genesis" private label made by U.S. divers for genesis. He agreed the one on the right is an older conshelf or aquarius.
Looks like I've got a couple of project regs on which to learn / practice my rebuild skills.
thanks again!

Check the serial numbers. First two digits should be the year of manufacture. Serials should be under the mouthpiece. I've got an old '74 conshelf(?), and wish I could find another.

You are right about the location of the serial numbers, under the mouthpiece. The numbers are "BR0A2330". Seems like it takes a knowledge of the "codes" for this one.
