I just bought a regulator on ebay and seller had no idea what brand it is, it has 3 dolphins on it. The 3 dolphins are apparantly jumping out of water two are just white outlines of the dolphin but the one in the center is all white. Does anyone hav eany idea what brand this may be? It has a Poseidon Din to Yoke Adaper on it.

Poseidon incorporates what looks like a whale on a fork.
I didn't know Poseidon was Japanese.
Poseidon the god dude is incorporated with dolphins in mythology.

Decribe the reg dude.
