I have this helmet i actually know the maker from the UK mando boards, it needs serious work, when i say serious i mean 5 + hours before priming.
For boba fett no chance its way to deformed and of poor quality, for a mando maybe i have been working on mine and it’s been about 3 days of work to get it to where i want it
The mandibles are wonky, the rear back plates are bowed due to poor casting, there are thin spots everywhere, sanding a tiny bit breaks though into the fiberglass, the ear cups are deformed not straight so impossible to fit the ear pieces.
It appears to be a cast of the RS Prop masters Helmet (which was cast from a MR)
I will upload some pictures for you tomorrow
never buy anything from eBay, everything is poor quality and requires a crap load of work
