The gem of information! Thank you. I'm off to find my horse collar and scavenge the cartridge... what a great solution for getting careful torque on a reg!
Ah I love this place.

Did instructors teach inhaling from BC long time ago?

In my first PADI OW course in Fall 1984 in college, we were taught to to use the bc as an emergency backup. I had a Seaquest with a CO2 canister back in the day.
Interesting, the single cartridge on my vest was really cheap in the early 1960s, maybe 10-15 cents. It was threaded, Aluminum, and about 5/8" OD x 3". A lot of kids had them for CO2 powered BB guns. The inflated vest probably had 10-15 Lbs of buoyancy and was only intended to be used on the surface.
I finally stopped wearing that vest when the Aluminum mechanism that punched a hole in the cartridge froze up from corrosion... but never told my dad about it or that reserve valves were useless in kelp. Those two items seemed to comfort him and I wasn't about to burst his bubble.

Well... I had to report back. It's a perfect solution, and I had a stubborn reg from two days ago I wanted to peek inside but set aside for later wrestling.
If anyone asks, this is why we are prone hold on to outdated things, they may be useful later. Just like bag breathing.
...corrosion needs some attention but I got excited to put the tip to use.
Anyway, thanks.

If you screw it into a 7/16" to 3/8" HP port adapter, it'll work on 7/16" HP ports as well.
Back in the 1960s when I started diving we didn't have BCs like today (although there were a few horse collars). Didn't use a BC until 1989 and was never taught this. Given the minimal care I give my BC, I'd have to be desperate.to consider this.
A little off-topic but related: Hose connections on first stages are industry standard SAE J1926 O-ring sealed straight thread ports. The HP 7/16" port is designated -4 or 1/4" and the IP ports with 3/8"-UNF threads is -3 or 3/16". You can buy cutting tools for these ports from machine shop supply houses:
7/16-20" Port, 0.838" Spotface Diam, 1/4" 00274779 - MSC
You can buy tube fitting connectors that screw into them or use a Swagelok-style 1/4" compression fitting by removing the nut and ferrule and slipping on an O-ring.
