What is this Mandalorian helmet/jetpack from? I found this flat silver &amp; blue Mandalorian helmet &amp; jetpack in a mixed bag of minifigs. I'm pretty sure it's not LEGO - there's no LEGO mark or part number and the only thing printed is the number "2" on the inside of the helmet.   There is no color on the jetpack.

All the LEGO Mandalorian parts I found online have the helmet and jetpack as 2 separate parts - this one has them connected. 

Can anyone find what non-LEGO set or figure this is from?  I didn't think anyone else had the rights to make Star Wars parts.
