Miles. I sent you my email address. I have restored both the Imperial and a Rocket / Princess. I can help you some.
Yep....that's the cylinder of an Imperial. Sent you an email.
After seeing your pictures you DEFINITELY have an IMPERIAL in need of restoration!
I can't think of anyone better to advise you on this than Critter!
Good luck with the restoration and if you decide to sell please let me know.
The easiest restore option would be to empty it's contents and refill it with glitter.
I think it would look awesome using fast moving large square holographic glitter from Kirk -
There were some Imperials that were filled with glitter instead of lava -
