A customer brought about 15 boxes worth of dive gear ranging a 40 year diving career that his father had. In one of the boxes was this piece. I got incredibly excited since it looks like it can be a part of a triple manifold but no searches online have helped so far. I know I shouldn't get my hopes up that I can use this for a triple set but now I'm just curious on what it is. Any help is appreciated.
As an aside there was lots of cool gear. Including some Piel micro regs and some Apeks regs from the 80s. along with some nice single hoses from seamless in good condition.
