However this identification information did not get communicated to some of the smaller shops at the start of the project. The letter “X” apparently was for all the other authorized shops. The letter “B” represented Bolsa Gunsmithing, “L” was Lefever, and “N” was for Nu-line Guns. Upon completion of the recall, the shops were to test fire the firearm and to stamp an assigned letter on the inside top of the receiver as seen thru the magazine well with the bolt retracted. Olin then also authorized other warranty gunshops to make the required alterations. There was a manufacturing delay in the replacement firing pins, and a BACKLOG occurred, also some collectors did not like the idea of shipping their guns long distances. Olin set up regional recall centers at three established US gunshops. The responsibility for the recall apparently was on Olin, as they were the parent company AT THE TIME manufacture. This apparently was caused by the firing pin tip (now not having the benefit of the retracting spring) to be stuck forward, and thereby slam-firing the cartridge upon chambering. The word was at the time this recall was in process was that if the firing pin would break at the mid section and still remain in the gun as two pieces, the possibility of a premature discharge before the bolt was locked was possible. Part number for the new parts are, firing pin =1391ND, bolt sleeve locking pin =1491ND Also replaced is the bolt sleeve lock pin (firing pin guide) which was made to accommodate this different shaped firing pin While the new recall style is similar in lathe turning on the front and back, but in the front midsection it has two flats milled, one on each side. The old replaced style, was totally lathe tuned (round). The difference in the old firing pin and the new one is as follows.

Can't recall what letter, but it varied depending on which contact shop did the service. Rifles that had the recall performed (replacement of the FP) got a letter stamped in that area. Now look down thru the mag well, at the top of the receiver, right above where the bolt would be when in battery.

Shine a light in the mag well, retract the bolt. Turn rifle so that the rifle is upside down. Besides customer service, and eyeballing the firing pin, there is another quick check (I do not guarantee this- if it is wrong I have 3 folks that will swear I was playing poker with them)
