iron buck - are you sure the grips are plastic? If they are real Sambar Stag and that old they will have a slight yellow patina that may make you think they are plastic. I would take them off and test them on the back side with a hot straight pin. Just heat the pin up with a match and then touch it to the back side of the grip, if it is plastic then it will melt, if it is real Sambar Stag then it won't. I would like to know, a real set of Sambar Grips like that are worth a pretty penny.
