Coincidentally my late father worked for Miller Triggers on a part time casual basis back in the 50's. His regular job was next door at the Brubaker Tool Company there in Millersburg, and he would stop in after work and lend a hand. (Probably because he didn't want to go home and find out about the mishief du jour I had gotten into!) I remember him saving his nickels to have a Miller trigger installed in his Fox.
