Found a person who has a model 99S in 243 that's looking to trade it for a 300 in model 99. Says his is a 60's version and that those are a "harder caliber"(in 243) to find. My 300 is an early 50's version I know condition plays a big factor in making the decision. But can anyone verify what he is telling me is true and what exactly I could look for to make sure it is what he claims.. thanks for your input. Also what year did they stop putting the schnabel forearm on? TY
