Hi, I got my hands on what apppears to be a Conshelf IV but the plastic knob just says US Divers. 4 LP Ports, 1 HP port with modern thread sizing. Serial number is: BBB3596. On my other Conshelf the serial # starts with xx- , with xx indicating year if manufacture. What do I have?
 
Sounds like a Conshelf 21 or 22. Same internal service parts as a XIV.
Thanks. Yes I do realize the service parts are the same and I already performed the service. Just curious to know what model it is and when it was born.

FWIW I have a Conshelf 22 that I purchased new about a two decades ago. It has the same port configuration and thread sizing. The knob is plastic and says US Divers. The serial number is ZMB0843. I agree with GJC, it is probably a 21 or 22. The Conshelf 14 has the same port configuration, but would probably wouldn't have US Divers on the knob.

My late model, late production 14 has "US Divers Conshelf 14" on the knob.
