I know that there is a maker of engines and parts but I can't remember their name. Hang in there John. I'm sure one of the guys will come through with the name or site. I thought I saved it but I just checked and I can't find it. I'll just have to remember to save it when I see it.

Just remembered. Check out Scale Auto. They have manufacturers listed.
Main WIP:
On the Bench: Artesania Latina (aka) Artists in the Latrine 1/75 Bluenose II
I keep hitting "escape", but I'm still here.
