Scott Number For These 2 Pairs Old Benjamin 1 Rotary Stamps?

both horizontal pair of rotary stamps measure perf. 11..( these came from the same lot of loose stamps that kind gentleman gave me). Can someone inform me what Scott numbers they are?

The top pair is Scott 632, perf. 11 x 10.5, rotary press.

The second lower pair appears to be Scott 552, flat plate.

What does the backside of the lower darker green pair look like? Are there some small light "splotches" of green on the back? Are there horizontal paper ridges?

I believe the bottom pair is flat plate not rotary, so your answers to these two questions can help determine the printing type.

Thank you so much, orstamp! yes, I noticed with 2 pair stamp under scan that has backing of little ;ine.very difficult with naked eye to view, so it definitely a flat plate. smiles..

Can you please scan or show a good resolution view of the back side? That would be very helpful for other viewers to see and provide their inputs as well. If there are horizontal lines (gum breaker ridges) they would be fairly easy to see.

Blazenstar, any time you ask for the identity of an older stamp please include a scan of the back. That is very important in identifying the printing method!

no problem, Peter..will do..smiles

..This is the first pair reverse sides of the stamps of the Scott 632



This is the second pair reverse sides of the stamps.

Oher information that may be helpful for viewers: there is no gum noted on the reverse sides of either one of the pair stamps. Thought it was rotary for the second see the several curve lines of cancellation in front faintly, that is why I thought would be interesting to get a better opinion from others. For rotary Press..In the Scott's Specialized catalogues it states." until 1914, only flat plates were used. After approval of plate proof, older rotary press plates required additional machining. They are cured to fit the press cylinder. "gripper slots" are cut into the back of each plate to cut into the back of each plate to receive grippers which hold the plate securely on the press." These two stamps were done in the 1920's.

Are you all going to make my day and tell me that it is a coil waste stamp for the below pair? (can I dream?) hahahaha.

You can dream, we all do!

Thank you Phil...smiles..

blazenstar - THANK YOU for the back-side views! I can now confirm that the first pair is the rotary press P.11 x 10.5 Scott 632 and the second (lower) pair is the flat plate P.11 Scott 552.

Keep checking and trying - the coil waste and rotary rarities are extremely scarce, but I'm sure there are some more out there still waiting to be found!
