Suspect Scott #355, Used Single.

This is an expensive coil if it were real - $300 catalog value and is often faked. This coil can be made by adding perforations at left and right to a trimmed #347 imperforate issue, adding perforations at left and right on a #347H imperforate coil and trimming the perforations from the top and/or bottom of a fully perforated #335.

The watermark is double line “P”, normal and reads horizontal.

The suspect is just over 24 mm on the left side and just under 24.5 mm at the right, way off the ideal of 25mm. The two cut edges are not parallel with each other.

The perforations were compared against genuine gauge 12 perforations and there are fit issues – see the images below.

  

the top and bottom edges are not parallel with each other.

Conclusion: In my opinion the suspect is a trimmed #347 with fake perforations added.
