I’m thinking of getting one of these two M40 helmets. Both are Quist M40s and are a similar price. Helmet B is slightly more expensive.
Helmet A has the chip strap, but a slight layer or rust coming through the shell. Helmet B is in a general better condition - the paint is very good.

I believe both helmets to be orginal for these reasons:
1) Paint looks the right shade for Quist helmet and has the correct level of roughness.
2) Both decals look good to me - the detail seems there on the feathers, the claws, the beak and eyebrow. The claws overlap the swastika correctly. I’ve compared to other 2nd pattern birds which look very similar.
3) Helmet B looks to have a lot stamp of 2×25 which is think is good.

I couldn’t see the lot stamp on helmet A. Also the only thing that concerns me a bit with helmet B is the worn liner which is perhaps not as consistent with the exterior of the shell?

I’m leaning towards helmet B because it does look pretty darn good.

Any opinions on either helmet and levels of authenticity are welcome.
Apologies for the size of pics - it is the best i could get.

Thanks in advance
Nick
