Hi Dean
I would say that the pin you have posted is a post-war reproduction, I am sorry to say.
Hoffst�tter pins were very different on the back of with the MM being stamped and the numbers are a different size and font.
The likelihood of them changing the whole production set-up for a small range of pins seems highly unlikely given their low value.
The only differences I do see on original pins is that some have the issue number engraved rather than stamped.
