Gentlemen, before I just threw these up and ask a ton of questions I used every resource you have provided me to do it myself. Lets see how I did.
Stamp on the left I believe is 1932 rotary press perf 11 x 10.5 with a precancel scott 720
Stamp on right was a real challenge, but I think this is a 1918 type iv offset perf 11 with a cancellation scott 530
Let me know how I did. Thanks
