5160 = microprinting "USPS" on right end of the fourth red stripe
5161 = microprinting "USPS" on right end of second white flag stripe
5160 is SSP/BCA and 5161 is AP.
I got confused! Your explanations are excellent. Thanks.
I have few stamps 5160 or 5161 with BCA microcode. Both have the same perforation types.
How can I decide what stamp is 5160 and what stamp is 5161?
Thanks, Virgil
