I don't think so because one corner of one fin in the back is broken off from the original crash. It was my first crash when I was 17 and it looks to be aluminum to me.

It has a huge air mixture screw for the visually impaired...lol

The other thing is I have no "documentation" on the engine so I don't know what the "initial" set points are for these needle values so that I can try and see if it runs at least. I built a board so I would like to test run a tank through and just see it run.

Its in good shape as I cleaned it, after-run oiled it and stored it in a paper bag to absorb oil and water and then wrapped in a plastic bag. It looks new except for the minor crash damage. No damage to the crankshaft though because it turns well and the compression feels stronger than a new OS 40 to me.
