I would like to try out a Magnesium Alloy mask. Two extremely similar models were put to market just a couple years ago (they were likely clones or copies of each other) from +POS and Champro. My preference would be the +POS, but I would not decline a Champro.
Once you contact me that you have one, we can discuss purchasing, lend-lease, or trade options. It's only crucial the frame is intact – if the pads are shot or the harness is kaput (or missing), no worries.
