Need info pirelli frogman rebreather mask?

[Mike Lev]

I picked up this Pirelli Frogman rebreather mask. Looks like a LS901.I have seen this style by Pirelli before but never with this chrome mouthpiece. All the ones Iv'e seen have a brass mouthpiece /valve with a small lever on one side. The hose comes straight out the bottom. This is set up for double hoses. Maybe for a double hose rebreather or double hose reg. Does anyone have any true info on it?

Hello Mike, Just a few more pics, maybe "Pirelli" used the mouthpiece"T" from either "Spora Sub" and or "Salvas" Italian manufactures the fotos might help to widen this posting.

Hello BJ you might be right. My mask doesn't have the piece inside to bite down on. A different set up. I think it was used for scuba only. Thanks Mike.
