Suspect Scott #349, Used Single.

This is a reasonably priced issue cataloguing for $90 as an unused single. This coil is often faked and can be manufactured from the following stock: adding fake perforations to a trimmed imperforate #344, adding fake perforations to the imperforate vertical coil #344V, trimming the perforations off the left and/or right of a perforated #332 and trimming the perforations from the left or right of the #332a booklet stamps.

The watermark is an inverted reversed double line “U” at the bottom and “S” at the top that reads horizontal. The horizontal watermark eliminates the possibility of the suspect being a #332a booklet single.

The width of the suspect is 20.75mm at the top and 21.0mm at the bottom which is a far ways off from the ideal 21.5mm. According to The Experts Book “most genuine coils will fall within 0.3mm of these ‘ideal’ figures.”.

The top perforations gauge out to 12.025, the bottom perfs gauge at 12.049, are parallel to each other but not the frame and are not a good match to the genuine perforations. The top and bottom perforations gauge outside the normal range of +0.06 and -0.085. The suspect’s perforations do not show evidence of being genuine. Flipping the perforations shows major fit issues.

The edges are rough and wavy but show no evidence of perforation remains.

In my opinion the suspect is a trimmed Scott #344 with the fake perforations added at the top and bottom.
