I bought this item more than 10 years ago in an auction as #10. Going back through my classics for a second look and this one does not compare well with my other 10's (Orange Brown color). Given the guide dot in upper right corner this should make it somewhat easier to plate. I looked through all the top of plate positions and given the positioning of the guide dot, I settled in on 5R1 (e and i) and 9R1 (e and i) as possibilities. If this is one of these positions then yes this would be a #10. This was all based on the dot placement and no inner lines. I looked at plates 4,6,7,8 and none of these had the dot placement line up with mine.
Any input or feedback of where I may have went wrong is appreciated
Thanks in advance.
