Doug,
That will be a great help when I convert the extra bolt I got for my SwissVetterli but the firing pin in question is for the Italian
Vetterli, They are very different. Italian is a centerfire one piece to begin with.
Seller said I can return it and he'll pay the postage. Not sure I want to give it up if it is easily converted. I'm figuring about 2 minutes with a belt sander and 5 with a drill and a file. Once done however, it can't be returned.
