I just bought a pre 64 Model 70 featherweight that has a recoil pad added. As close as I can tell, the recoil pad says on it:
Paso Robles, Calif
The rifle is a 55 model and the pad is still flexible. According to the seller his dad bought the rifle new and had the pad installed soon after ( a year maybe ) the purchase along with having a couple of other things done to it. One thing that was also done was to full length bed the barrel channel on the stock.
I have never heard of this particular brand of recoil pad. Does anyone know anything about them?
