Adding pics into this thread...
Thanks Brak's!
It seems this prop was made in-house by ILM for ROTJ.
I suspect the parts used come from kits that ILM was known to use during this time period.
The side detailing does look like tank tread, but does not appear to be the same 1/48 Panther tread used on the Thermal Detonator prop.
What other tank or treaded vehicle model might this have come from?
Necro-bump for an old post.
Maybe anyone has new insights by now
Any information about model and scale of the possible donor-kit would be awesome.
Many thanks in advance.
