Suspect Scott #315, Used Single.
I bought this stamp on EBay as a known fake with the goal of getting it off of the market and doing a proper analysis on it. This stamp is uncommon and is very expensive with a catalogue value of $1250 in used condition. This stamp can be easily faked by trimming the perforations off of a fully perforated Scott #304.
Looking at the top and left edges there are what look like remains of perforations, the the images below.
Conclusion: In my opinion the suspect is a Scott #304 with the perforations trimmed off on all sides.
This goes to prove that the best way to collect imperforate issues is as a pair, block of four or other such multiples.
As always comments and suggestions are always welcome.
