Sierra 756 Mask + Mystery Mask


Recommended Posts

Hi all,

 

Recently won this partially complete version of a 756 mask. It seems to be the alternate setup with a side mounted hose that has much more in common with an MBU-20/23.

 

As part of the group, this strange black mask and an MS22001 were also included. Any idea what the black mask is? Is it US, Russian, or otherwise?

 

Best,

Matt

The solo hose looks like a MBU-5 hose, has the long top as they had a long inhale/exhale valve. Not sure on that mystery mask, Id say def not Russian as it doesnt have their usual cloth hose. Looks like someone messed with it adding that cheap rump hose clamp to the end as well.
