I think several brands ship out the same door of the same factory, but are distributed in different countries. We have Magnums, Australia gets ASP's, and I think England gets SC's and ASP's. I know Just Engines sold ASP's, and I seem to remember hearing about SC's in England. JE also sold LEO engines, which looked sorta similar, but different. Maybe SC's are relatives of the Magnums, and maybe they're something else. How about posting a picture of your .36? I'm curious.
If these engines all do come out of the same factory, I'd think that older tooling might become another brand, but then again, maybe they're all exactly the same. Personally, while it is always interesting to play with an unusual engine, when it comes down to getting it to work

, if you have almost zero chance of finding others with experience with that engine, you may come to regret the urge.
