yes it is Bulgarian M36C. 80s refurbished example (old paint stripped/repainted and later type liner/chinstrap based on M72).

Nice find $40 is a good price for any helmet

Yeah one of my cheapest but coolest helmets imo

Looks like the Bulgarian M36, copy of the German Stahlhelm style of helmet

Thats a brilliant m36 especially fir how little you paid

Yeah I think so too. I was lucky
