Found this old one in a dusty box last year
It’s a Comet Miniatures casting from circa 1989 I think, approx 6cm long so its very small. I think the tail was separate and recall drilling out the engines. Paint would have been Humbrol back in the day.
I might strip it and repaint, perhaps with some TLC to the engines.
I’ve also got a Space Shuttle with Crawler in same range still unassembled, may have to give that a go too.
