Franklinstein 1c Nightmare.

I know you all must be sick of my posting the Franklin s.

nope....

If you insist on searching for a perf 11, rotary press Franklin, rather than drive yourself nuts with a ruler, get a cheap rotary press Franlkin, such as the perf 10 coil (cat value @.20) and cut the corners off of it. You can lay it on top of a perf 11 1c and you'll see that on 9,9999 out of 10,0000, the frame lines will not line up. It's much quicker and more accurate to do it that way.

its not that insist.. it is that I have about 1600 of these suckers.

so far.. 60 that are dark green with 11x11 perfs.

does the top of the cheap stamp have to be perf. 10

It can be any rotary press stamp with the right image dimensions. You don't care about the perfs on the "tempalte" stamp, just the image size.
Your target stamp has to have both the right perforations and the right image size to have a winner. If either the perforations or the image are off, it's one of the common stamps.

If you want to make your life easy, you'll also have a perforation 11 stamp that you can use to line up the perforations. That will spare you from needing to measure the target stamps individually. (Take a cheap perf 11 stamp and write "11" on it in marker. Keep it with the rotary press stamp with the corners cut off as your guides.

Does that make sense?

top number first, side number second...
the cheap ones are 11x11 (scott 552), 11x10.5 (scott 632), 10x10 (scott 581)
the good one is 11x10 (scott 578)
the excellent one is 11x11 (scott 594)
the best one is 11x11 (scott 596)

so if the top is 10 or the side is 10.5 it is definitely cheap.

Ha! And no, I don't mind these posts at all... this whole series (or series of series) is fascinating to me in this day due to the fact the USPO stuck with the same designs for so long. Even the 2-cent blues of the same era had a sameness to them that you wouldn't see now. It's like one long forensic examination.
