Awhile back, I had done a quick ID on this stamp and was sticking it into my album, when I noticed it had serpentine roulette instead of perforations!

I don't see anything listed in some of the major catalogs about serpentine roulette for this stamp (Scott, Michel, Facit...) and I cannot seem to find it among the forgeries with the info I have.
I'll leave the window completely open for possibilities, and ask members to help me identify the stamp (original, re-issue, or reprint) by any catalog number if genuine; or let me know which forgery if it is a fake.
Thank you!
