Does any one have any pictures of the devices standing next to the speederbikes in Return of the Jedi. I have some pictures from the movie, but cannot determine the horn part. (trying to make an 3D model out of it, for my speederbike diorama)
It’s not the same, of course, but if you search corrugated drainage products, you might have some luck. This stuff gets redesigned every decade or so, for some reason, or new products get developed.
Offhand it looks to be about 12” internal diameter.
