Hey Chris! The helmet looks pretty good, although this was originally intended for an ESB (the physical scratches on the left mandible and on the left cheek, but also the viewfinder on the rangefinder), you can easily do some adjustments to look more like a ROTJ helmet:
1 - Remove the viewfinder from the perspex block (the ROTJ helmet does not have it)
2 - the 2 LEDs sticks out too much from the rangefinder casing; if possible try to fix this too.
Did you by chance purchase this from someone in Italy?
Looks great mate
