US 449 Or Something Fabricated? But From What?

These are two of my candidate rotary press 2c 10H stamps.

The first stamp appears to be Type I and the design measures almost exactly to the second stamp. In other words, they appear to be the same dimensions. I have also used a flat plate template, happens to be a 1c green, and the design is noticeably taller and a bit wider on the 2c. The second is a Type III and I have identified as #450 with positive single line watermark. The only 2c Type I rotary press 10H is #449. But could it really be that? The color is supposed to be red, but the stamp I have here is not red. The right edge of the first stamp is very rough, so thought perhaps it could be trimmed, but I could not find a possible stamp that is also rotary press and Type I with perforation 10.





I can post more images, side by side and /or backs if needed.

Side by side and the backs. The Type I has pencil notation on the back that says both #442 and #449. The design is showing through on the back of the Type I, but otherwise I don't see any setoff that I would normally see from a flat plate, unless it is very very light. Could a #442 (or perhaps a trimmed 425 or 463) really be this size?

Type I only comes watermarked. And your stamp is type I.

That would be true if rotary press. Are you also saying you think it is rotary press as well?

You only have two choices, 442 or 449, and the answer fully depends upon the veracity of your printing method determination. Can you show us the patient with your template(s) in use?

I created a new template from a #406 which is flat plate of the same design. It's not perfectly aligned, but it's close enough to see that the stamp underneath is noticeably taller and likely rotary press?

The 425e booklet pane stamps are wider than the 425 sheet stamps. Here is a used #425 overlaid on a mint 425e flat plate booklet).


Edit: to add the rotary press coils are wider still. See how the solid wide right margin intersects on the overlaid (used) flat plate stamp versus the rotary coil underneath.


Bottom line, I think you have a single from the left side of a 425e booklet pane that has had the right side perfs trimmed off.
