Hello,
I'm trying to figure out the town name in this cancel, but so far have had no luck. I don't have an image of the whole cover, but I believe it was mailed to Iowa or Nebraska.
The stamp is from plate 5L (97R5L), so it almost certainly was mailed in the 1855-57 year range.
The letters that I can make out appear to be OOLCRA or OOLGRA, but I'm not sure about the R and A.
Any help with figuring out this town would be much appreciated.
