conshelf us divers aqualung

Hello SB, I've recently been tinkering with a set of USD metal second stages, Conshelf supreme and deepstar 2, I got in a steal of scubamuesum. These paired with a pair of conshelf se2 first stages I got when I first got into diving, I making a pretty sweet looking retro single hose set-up...

so i randomly get people donating those old us divers first and second stages, cause they retire from diving. they mostly look like different versions of the conshelf style, with the us divers logo. is there a resource to cross reference these older models for compatibility to newer aqualung...

Based on recommendations I read on this board I went out and bought two sets of used regulators A Conshelf 21s (rated for cold) and a Conshelf SE2 (seems highly rated by members) They both seem in great shape, externally at least, and both have spent the last decade in their respective owners...

Hello all, I'm looking to buy Conshelf metal 2nd stages, preferably XIV or Supreme models. If you have one or a full conshelf rig you'd like to sell just let me know and maybe we can work something out. Thank you.
