Hi Ray,
It's 18cm high. And no I don't have a catalog number but there is a pencil number on the bottom. I'll take a pic and post it, maybe it's a model number ?
My guess is it's 1920 or earlier, mostly because of the wood base.The color would be a good clue also to compare to engines or ?
I think it was one of the first German pieces I bought and it came from the UK. I like it a lot because of the wood base and the J.F. badge and it's quality. I've never seen another one, but I don't look much.
Bob.
