Is there any mfg. name, model number, on the inside? I'd be surprised if there wasn't.
I've found a lot of old toy cars and there's usually something on the inside.
Thanks Jewelerguy keep me updated when the site comes up. Watercolor there is no marks on the inside, I cleaned it and it has nothing. It believe it is too old to be matchbox or hotwheel, original color was a green, thanks again for all the help.
