Welcome to the forum. Looks like you have two M42 relics.
Why not try to find an original and complete helmet in reasonable condition? No offense, but I've never seen these as all that worthy of collecting. Others think otherwise. I imagine finding these yourself would be quite thrilling though and would be quite an adventure.
I was thinking along the lines of possible restorations.
In my honest opinion I don't think either one is restorable sir.
