This looks to be a silent precancel. I'd like to know if it is or not. any help would be appreciated.
Bottom bar is about 1.5mm thick; 2nd bar up is 1mm although it is a little thicker on the right side of the stamp; 3rd bar up is 1mm. A portion of another bar is barely visible on the top perforations.
Distance between bars from bottom to top are 7-7.5mm; 8mm; and 7.5-8mm
