I generally stay away from manuscript cancels, but the stamp below was offered at a nice price, and I thought it was just too exceptional to turn down. The colors are vivid, the margins are wide, and the centering looks to me to be XF-S. It doesn't have a certificate, but I saw no faults after dipping it; hopefully the PF will agree.
My question is about the manuscript cancel. Was this still a common practice in 1869? I couldn't find very many on Pictorials with manuscript cancels in auction records, but maybe that is just because they are viewed so negatively.
Is the cancel on this stamp distinctive enough that someone can tell me where it might have come from? Also, the cancel leaked through to the reverse side through the grill points. Will this be considered a fault?
