Plating Help - 1851-7 US 3c (Scott 10-11)

Can anyone help me out here - I'm completely inept when it comes to plating the 3c 1851s.

Found this stamp in my album from back when I was collecting us stamps. Now curious as to what the plate might be (and yes, I did see that it has a green cancellation - that's what I think attracted me to it).

Thanks in advance.

Wow, that is the sharpest impressions I've seen (in my limited experience). On my computer screen it doesn't look orange enough to be #10. Plating it is still well beyond me.

chipg's stamp with the black and white levels adjusted (not much of a change) is in the middle. My #10 identified by date from it's attached letter is on the left. Original, non-adjusted chipg stamp on the right:



People much better at these than I am tell me that mine is an unusually pale printing. To me, the color is close enough and has the detail necessary to make it a #10. Setting the color levels will make an image more accurate to true color, but isn't as accurate as scanning the two stamps at the same time.

I'm still not educated enough to give a plate that it likely came from. It is a beautiful stamp and I do love green CDS.

-Edit: Ignore my color comments above. I sometimes work with my monitor's brightness turned down very low. Now that it's at a more appropriate setting, it does appear to be the wrong color. However, it is a very detailed printing.

The stamp is from position 26L1L.

Thanks, Sinclair.
It's a nice stamp and I was wondering what it might be. I kind of thought it might be an early printing of a later plate, as the impression is so nice.
Owe you one.
