Have you ever come across an "A" sticker sample? Someone in one of the other threads noticed that "Fifth Anniversary" He-Man came out in 1986, which might possibly indicate that some figures may have been released as early as 1981.
I can't tell if it's dipped or sprayed, either. 8-back with warranty could go either way, although I would lean toward sprayed given the timeline as well as how much of the top boot is unpainted.
How can you tell it's short strap?
