The helmet shell looks fine to me. The liner pads seem to be the M16 type on an M17 band. Not only are the pads supposed to be white, even if they did substitute the leather the cut or design of the pads in the M17, from the M16 is a little different. It is possible that they used the M16 pads in some production of the M17 liner but then the rear pin is missing or not going all the way through. All the parts look good to me so at worst it's a parts helmet. If the right price it would be worth picking up.
