You can have them free of charge. I have the trigger plate screw,top tang screw, and rear tang screw. They were ordered as a set from Galazan, but never used. I stepped in a stumphole while hunting wood ducks in a beaver pond, and my Sterlingworth and I both went under. Took the gun partially apart to aid drying, and lost a screw in the process. Later found the missing screw, so did not need the three screw set I had ordered.
Them beaver ponds are good at that, eh Beagle? Step in one deep enough and you get what we call "floatin' yer hat". My son and another boy were going in one years ago and he was following the other boy. Other guy, who was short anyway, stepped in a bad one. My son said his hat floated.
