Buy her a dozen viton o-rings and tell her she sure has nice brass.

Edit: I'm sorry, I should have read more than the tittle.

The US Diver's Conshelf XI debuted in the 1970 catalog, and was replaced by the Conshelf XII in the 1973 catalog. The first stage featured 2 LP ports in 3/8", 1 HP port in 3/8", and the middle generation of second stage which featured a 7/8" exhaust valve and calypso styled exhaust tee which screwed into the bottom box.

We talk about this all the time here:

Oh yeah, and that old crap will kill ya.

Dude,

Any USD guy will be able to rebuild that for you. Heck, if don't want it I'll take it.

no, that's alright. I just talked to my local "usd" guy and the cost of a rebuild is surprisingly inexpensive. I bought the thing as a "curio/relic" but am now thinking about what else I need to fleshout a Circa 1970 Dive set-up

Yep...that's how it starts. The first hit is free and then when you get hooked you just keep paying and paying until pretty soon the whole dive locker is taken over by vintage gear and no matter how much you buy, it is never enough.

Madness.

It probably works just fine as is. That reg is pretty tough.
It is an easy reg to work on.
