I was going to hold on to these, but after a few years it gets a little silly...
1st set were original on a model 57. The finish was sketchy on otherwise great grips (no wear on the checkering/wood). I stripped the original finish an used many coats of straight teak oil followed with gunstock...
When I started, I took some advice I found here and purchased a Factory Reconditioned Lyman Orange Crusher for $75.00 I think. Built like a tank and has worked out very well for me.
I also stepped up and got carbide dies.
I turn out 50 at a time and I do it in stages over a couple of nights...
