I have quite a large 1:285 collection acquired from various sources, I split my storage by nationality so I took my leopards from CiNC (
www.pfc-cinc.com) and used them for my Canadian forces. They don't look the same as the GHQ ones (which I use for my German forces) so it is easier to separate them.
The guy who made this page also used the CiNC ones
