A StuG:
Your "StuG" jack looks more like the Tiger jack (I
think it was the Tiger - I'm not really interested in memorizing what the
wrong parts look like). It certainly seems to be mounted on a StuG, in the same position as the fuel can in the above image. Whether it's mounted on a
Bandai StuG or not is a different matter; the Bandai box art has a jack like my picture. Checking out websites devoted to R/C tanks, it seems that the Bandai kits
have been heavily reworked over time, apparently. Perhaps your jack is from
a StuG kit, but not from the one that ILM used. Alternatively, perhaps the jack ILM used
is from a Hummel, but
you were the one that claimed that the Hummel part hadn't been retooled. Notice how the two smaller circular bits on the Hummel jack appear to be a little too close together compared to the part on the X-wing, and notice how the bits in the StuG picture above appear to be slightly further apart.
Another StuG jack, this time mounted the other way around:
Notice the thicker wall and the extra details. Again, it's hard to tell from the low resolution of the image, but it looks as though the extra details are holes. Look at the Red One image I posted, and it's easy to imagine that the details on there are laid over holes. There's no evidence of any holes in the Red 2 picture that you posted (thanks for that, by the way, I wish you'd post more like it) but I think that the hole is for stowing the jack handle. The detail on the Red 2 part might
be the jack handle. Notice also on your Red 2 picture that the large hole with the teeth doesn't have any lip around it - the hole goes right to the edge of the wall. The Hummel part has a lip.

Either state facts around here, that is PROVE without a doubt your information is 100% correct or keep the amateurish speculation to yourself. Guessing doesn't cut it. At least post pictures that merrit a discussion or an investigation."
Everything I've stated
is a fact, based on careful observation of the images that I've found. Your claims ("extra layers of paint make the part look that way" for example) seems more like "guessing" to me. There's really never been any need for your unfriendly tone.
I could easily be wrong - the StuG models that I've posted pictures of could have been accurized. Maybe the actual kit part
isn't the right one. So, I'll say it again. How about a gamble: The price of the kit? If I'm wrong, you make several hundred dollars. If I'm right, you get the right parts for the X-wing, and just maybe some more parts for your Y-wing. How can you lose?
