I think it’s called Craftman’s these days, it comes in a yellow tin. I originally got it to remove the nitro lacquer from the neck of my Roadworn P (I don’t get on with fairly new nitro, it’s often too sticky) IIRC and, as the paint was starting to wear (and be sticky) on the SUB, both got the treatment. I resealed with Danish Oil (2 or 3 coats, knocked back with wire wool each time).
