There are a lot of different ways to collect Masters of the Universe figures. You can collect by wave (first, second, third, etc), by line (original, New Adventures, 200x, Classics, etc.) or by character. You can also collect by country of manufacture, which starts to get into some pretty esoteric territory. Some collectors have very impressive shelves filled with dozens of the same figure, each from a different country of origin, and each with slight differences in appearance.
One of the most interesting of such variants is the made in France Man-At-Arms, shown below:
The most interesting thing about the France variant is the little cuff at the end of the figure’s armor at the wrist. That detail was included in the Man-At-Arms prototype (below), but it was cut from the production figure. Somehow it made it into the France version.
There are other differences compared to the made in Taiwan versions (which were the types most commonly sold in the US). The plastic on the France version is cast in much more vivid colors. The feel of the plastic itself is quite different compared to the Taiwan release, and is somewhat waxy to the touch. The paint on the France belt also tends to be uneven,and the boots and loincloth are a much darker color as well.
There is another French variant from later on in the run. It’s a version with enlarged boots (like Thunder Punch He-Man‘s). However, the boots are separately molded pieces, and are cast in a very rubbery material:
The “rubber boots” France figures also include Battle Armor He-Man, Tri-Klops, Jitsu, Fisto, and possibly others. Also notably (thanks to Dani Ramón Abril for the information), some Spanish releases of Man-At-Arms use the early French mold, down to the “France” stamp on the back.
