It's a full face Fisher & Paykel, but not Forma, 431 or 432. It has no model name on it (like where the Forma says Forma), only Fisher & Paykel, and then near the top on the bridge to the single forehead contact it has a circle with a 2 in it with a line through it. It has a silicone mask but no foam liner. (Mine is a size small, if that makes a difference.) One thing that most distinguishes it from the other F&P ffm models is that it has two prongs sticking out to either side of the hard plastic part to the sides of the nose.
I didn't get any documentation with it (bought a while back from ebay or Amazon marketplace). Should say my DME is perfectly useless. So I'm hoping one of you folks might be able to identify this. Thanks!
