This regulator was donated to my club and I bought it as I recognized it was an S600 2nd stage and DIN, which I dive. I don't see the usual MK25 ring which appears to be missing and also want to get an idea on the age. Please direct me to where I can get parts or if someone here has the missing parts it would be greatly appreciated. Hooked it up to the tank and IP is good, but will get checked out before diving with it. Thanks in advance.
