Delta Super J?

[LosiRacer1]

Got this guy last week. Thought it was a Delta Super J? Maybe it is with aftermarket parts? It has an aluminum rear wing with wing strut that I haven't seen anywhere and the steering blocks are nice aluminum too. Just aftermarket? Or different model?
Thing is quite clean, just been sitting for a long time.

I have this scan from an old catalogue which may help.... or may just confuse further

I think it's a Delta CK760. Is the chassis painted? Looks like it.

I don't think so, I'll double check when I get home.

I'm honestly not sure what it is? It definitely has a coating on it, but not 100% sure it's paint? It feels and looks thick. There a couple of very small chips in it.
Plus check out that wing mount. I can't seem to find anything about that anywhere.

Could be lead paint. The bill that banned lead paint passed in 1976 which is the same year that that CK760 wouldve been raced.
