Wide Rotary 1 Cent Franklin

Hi, I need some advice on a 1 cent Franklin stamp that I can't identify.It is 11 x 10.5 Perf. and measures 19.5 x 22.80mm
The stamp is shown on the left of the image and I placed a 632 Franklin next to it for comparison(both taken from the same scan). I used a 5 cent Myron's Discobolus stamp (also 11 x 10.5) to measure the Perfs. Thank you!

Since both have the same stamp design measurement and both are perforated 11 x 10.5, the stamp on the left is 632 green and the stamp on the right is 632 yellow green.

Thanks, the design measurement of the 632 is almost .5mm narrower than the stamp on the left. Does the width of 632 Franklin's vary or should they all be 19.25mm?

While the Scott U.S. specialized catalogue gives a stamp design measurement of 19 1/4 x 22 1/2 mm for these rotary press sheet stamps, this is an approximate measurement only. The compound perforation 11 x 10.5 only comes from a web-fed two-way bar and wheel perforator that was and could only be used for perforating web-fed rotary press printed sheet and booklet postage stamps. The 11 horizontal perforation (Kiusalas 70 = 11.25) was made by rotating perforating bars and the 10.5 vertical perforation (Kiusalas 75 = 10.5) was made by rotating perforating wheels. This perforator could only perforate rolls of rotary press printed postage stamps only both horizontally and vertically in one perforator as well as cut the rolls into big sheets and apply gum breaker lines on the stamps. The order in which all of this occurred was gum breaker lines, vertical perforations (wheels), horizontal perforations (bars), paper roll cut into sheets (not panes). [On the other hand, two sheet-fed one-way wheel perforators were used to perforate sheet-fed flat-plate printed sheet and booklet postage stamps with one perforator used to perforate the horizontal perforations 11 (Kiusalas 72 = 10.94) and another perforator used to perforate the vertical perforations 11 (Kiusalas 72 = 10.94). These perforators also cut the printed sheets into panes. This perforator was also used to perforate 11 x 11 rotary press printed sheet and coil waste. These were from leftover, remaining or damaged parts of rotary press printed web rolls that were salvaged, saved, trimmed and cut into sheets after printing and sheet-fed into these perforators instead.]

Hi Stump, and a very welcome to this forum. The width of these stamps ( and others as well ) can indeed vary quite a bit, mainly due to paper shrinkage. The size of the printed area is not a good indicator of the catalog number.

Thanks again for the welcome and taking the time to explain. I will keep this in mind for future reference. Great forum by the way!
