I pulled out what I think are OB examples used in each month of 1851.
Sorry the scan is backwards. That's July far right.
As you can see I'm hedging on the July. The stamp is plated 94R1e. So it was printed Early in July. I'll use that stamp to mark the spot until I can find one better.
The Aug stamp I'm not certain on color. I would need to plate it before I lock it in place.
The Sep stamp I have plated as 22L2e.
Just thought I would share this mini display.
