This is supposed to be Mailometer Type 2. It hole sizes are perfect (1.95mm each) but the length of 7 holes is off from my reference (which is Belasco's book on Vending & Affixing Coils). Belasco states that the total length for 7 holes should be 20.6mm. Mine is 21.0mm. I assume this one is likely a fake, but since the holes are right and the length is off <0.5mm, I didn't want to finalize a "fraud" verdict without posting it here.
