FNB Parts Grant F. M. Goddard Bigelow December Browning 1, 1950 I find that the factory is periodically confused on the interchangeability between several different automatic parts as shown on our parts list. In general, we tend to show parts as interchangeable where they are actually not according to the production records. In such cases it is very likely that we sre in error, Probably what is happening is that the shop has found that by minor alterations of a part, it is able to make a part which strictly belongs to only cne gauge work for both gauges. When we send an order to the factory, however, we should order strictly according to factory parts instead of according to our method of adaptation and conversion, I’ find the factoryJ B20 B52 B76 Delvaux asks further delay is + Carrier confused now Latch Screw, on the followings g 12/16 = Locking Block Latch Spring, - Safety Sear, 12/16 Gauge me whether in we delivery, want 12 I have or asked 16 three pparts: Gauge 12/16 Ga. cauge him follows: B20Carrier Latch Screw, 12 Gauge 20 = Carrier Latch Screw, 16 Gauge B52 ~- Locking Block Latch Spring, 12 B52 - Locking Block Latch Spring, 16 B76 - Safety Sear, 12 Gauge B76 = Safety Sear, 16 Gauge Gauge Gauge 1,200 400 Think it would be a good idea if you could have Harry go through our master parts list and asterisk those parts which we show as interchangeable but which actually from the standpoint of a manufacturer are made with different dimensions even though the dimensional difference may seem to us trivial (such as the difference of a fraction of an inch in the length of a screw).
