Unfortunately, dies modified to fit Rowley
machines can NOT be modified further. Their openings can NOT be enlarged.
Modify Die for Hoppers and Canvas Backs
Osborne #16, #18, #20, and #22 button dies have inside diameters that are slightly smaller than standard (this has nothing to do with "Inside Opening"). We can modify these sizes to meet modern American standards so that buttons from other factories (hopper backs, canvas backs, etc.) can be used. This modification should not affect the function of the die and is unnecessary if you only plan to use wire eyes (or are ordering a die larger than #22). We used to offer this as a complimentary service but rising machining costs no longer permit it.
