Oxygen mask help
I am looking for a used mbu-20 oxygen mask. Does anybody have the dimensions for choosing the offered sizes. I have seen a chart once...but for the life of me, can't find it since. Gentex offers small wide...medium narrow etc, but no sizing chart. I don't want to eBay purchase one that is the wrong size.
if anybody has one for sale....please feel free to let me know as well.
I am building a fresh air system for civilian rotary wing...so the mic, cords, and pressure system tubes are not required.
Thanks!

Thanks Nutloose,
I had done the "quick" search....on the gentex site only gives the part numbers....not the actual part number vs the size/dimensions of my face.
There must be (I have seen one done in a red diagram) a chart so you know what size to order, based on your personal dimensions.
