I keep seeing this space tank around.
This one is a Japanese toy.
By Bandai, the auction site it was on listed it as "Space detective shalban shillinger tank CARICOM RC"
The same tank comes as a basic space toy as well, which I've seen several times on Ebay, but for the life of me I can't find one now!
The basic shape reminds me of the front cab of the Project SWORD Buclear Ferry, especially this illustrated version by Mike Noble in Star Fleet.
