Suspect Scott #350, Used Single.
This coil is often faked the catalog price for an unused HH #350 is a modest $210.00 and can be faked by adding top and bottom perforations to a trimmed #346, adding horizontal perforations to a #346V imperforate coil or trimming perforations off the left and/or right edges of a fully perforated #334. There is no booklet stamp from which to fake this issue.
The watermark is single line “P”, reversed.
There is no need to go on with the analysis, a genuine #350 would be double line watermarked. The suspect being single line watermarked can only mean that the suspect is a #377 which is single line watermarked and perforated 12 on all four sides.
Conclusion: In my opinion the suspect is a #377 with the perforations trimmed off of the left and right sides.
