My father worked at the Brubaker Tool Co. next door to Mr. Miller's shop in Millersburg, Pa., during the 1950's and early 60's. Quite often he found part time employment with them stoning and fitting parts. I think it was more an excuse to hang out there. A lot of local working class guys had Miller install his trigger on the doubles they scrimped and saved for which may account for the decent number of nice doubles that turn up in that neck of the woods.
