Scott Specialized says that the R153 with an altered leg of the "R" and square periods occur in positions 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
I have a block of 9 with the three right R153's having altered R's and square periods. Is there any way to 'block' these in the plate or sheet?
There appears to be a position dot underneath and to the right of the upper right hand stamp.
