Not sure of the number but it was a semi gloss as far as I can tell. Nothing I've seen looks full gloss, but then it has been almost 50 years. Used to use something we called "Holden 60/60 low sheen" for any of that sort of thing. Same as on the black bits of a Torana etc. This was proper acrylic, not crappy chassis black.
I got a couple of NOS Standard hub caps but I had to blast and paint some chrome ones too. The painter said "sure you want to wreck this nice chrome?". Too right I did. 👍
