Subject EF To Mr. AT ra N ° B s Parts Order M. Bigelow Reference December 1, 1950 Date December 7, 1950 o Browning From The factory for those Why 12 these and 16 is correct in that there are items listed in your memo of three items have gauge is a always mystery, as separate 12 and 165 gauge December 1. been shown as interchangeable the gauge parts 12 always used parts between have had to be adapted by the shop. Apparently Mitch, when setting took these adaptations for granted when actuallywe should ordering these particular parts for both gauges. The fact up these lists, have been that these items Ken are not interchangeable who has close contact never been confronted each gauge. The breakdown of the with with new is the the even more amazing because himself, parts problems and with the shop, has fact that there were separate parts for order as to quantities of 12 and 16 gauge parts is satisfactory. These parts will be set up in our inventory record with a suffix of a’for 12 gauge and"b for 16 gauge, When the interchangeability list is reprinted, this correction will be included. I had Harry review our interchangeability list and, with the exception of the Cartridge Stop Screw and Magazine Cutt Off Screw, the three items in your list are the only parts which we show as interchangeable but which actually, from the standpoint of a manufacturer, are made with different dimensions. Harry pointed out to me that the 16 gauge Carrier Latch Screw is about 1/32" shorter than the 12 gauge screw. The shop has been using the 12 gauge screws in 16 gauge guns by grinding down the 12 gauge screw. The same also applies to Cartridge Stop Screws and Magazine Cutt Off Screws, as all three are one and the same. The 16 gauge Locking Block Latch Spring is thinner wire and about 1/16" longer. The shop has been using the American spring for 16 gauge models. The Parts Department has been sending Belgian 12 gauge springs to the trade for all needs. The amazing thing is that as yet no complaints have been received from the trade. Of coursewe should stock the 16 gauge spring and fill orders properly. The 12 gauge Safety Sear is slightly longer in length and the shop has been trimming down the 12 gauge sear for 16 gauge guns. For the trade the Parts Department has always sent 12 gauge safety sears for all requests. Amazingly enough again, there has never been a complaint. Apparently the factory overlooked our showing these items able, as I believe we sent over copies shortly after they prepared for their review as to correctness. GFG:ed as interchangewere originally
