320 Or 320A Carmine Or Carmine Rose

I beg the indulgence of the forum as I try to make sure I'm identifying these various stamps accurately. I have the two below that I keep going back and forth on based on a close-up view of the lower left corner. Would either of these be 320A as opposed to 320? The colors are also a bit different - is that normal variation for a 320 (if it is that) or is one of these a 320c carmine rose?





Again, greatly appreciate any advice from more knowledgeable and experienced folks.

Hard to tell from the images, but there are two Types for this stamp as shown here http://stampsmarter.com/1847usa/1902/319.html
