Just looking for cheap dated covers in my quest to find some of the unlisted shades and saw this damaged cover for $26, and didn't hesitate for one second before I bought it.
I've already forwarded it to one of the experts on VSC, and he has shown me a few pigeon bloods, and he also thought this has a chance:

No year date on the cover, so no way to prove it's 1861, but the October cancel could work-- the pinks were in Aug/Sept/Oct of '61, and the stamp has a really rich color.
So, I thought I'd post it and see if any of the other color shade guys have any thoughts on this one: Ron? Winston? Love to hear what you think on this one.
Of course, there's always a huge chance that the color isn't the same when the stamp is in hand as on the screen, but this one looks like pigeon blood to me, compared to a couple out on
ebay now (especially looks close to the 3rd one, from Wm Langs on cover:



So, I should have it in hand in a couple of days-- wish me well here!
Thanks, Ray
