I've been sorting through an envelope of Washington-Franklin coil stamps and wanted to see what people thought about this one.
It is Perf 10 vertically.
It is Rotary Pressed.
It appears to be a Type II
I cannot find watermark.
Assuming all 4 of these criteria are correct, then this would be a #491. 491 is a rare stamp so i'm questioning wether I missed the watermark* or I am incorrectly identifying it as a type II. What do folks think I have here? 454 or 491 or something else? I am posting several images of the stamp in question.
* When I stare at the back of this stamp while in fluid I can see what one might construe to be an "S" just above and to the right of center. I think these are the cancellation lines showing through the stamp.

Here's my check to see if it is a rotary.
