Side view of a 20 year old reproduction Mark V helmet.


1. Faceplate wing nut does not seat with a tapered fit as in authentic Mark V's, but is squared off on the seating end.

2. The spacing of the exhaust holes in the banana valve is irregular and the holes are smaller than those of an original.

3. Absence of dumbell lock which should correspond to the slot in the lower neck ring.
