Auto Two Shot Browning Yours of July & -— the to believe that the FN only instead of taking ment distortion, link you sent has not preference is correct it all the way to the yet arrived, but I am inclined in moving the cut back 4 mm, rear on account of heat treat- You are probably right about the forearm latch of hiduminium, but one thing is certain that the latch cannot be any heavier than as originally designed, preferably lighter since you know that these latches jump unlatched by their own inertia in the proof tests, which indicates we are on the verge of being too heavy. This would be disastrous if we had a single one of these latches jump unlatched in the hands of a shooter. The barrel would jump out, and we would have a black eye that would be a long time healing. This is important. I have even envisaged the possibility and desirability of putting a little lock on this latch to maintain it in place. Regarding my cable of July 10, the word section should read friction, but the text is so evident that I suppose you have understood it. I think you are probably right that the contact of aluminum against steel under conditions of momentary intense frictional heat caused the formation of oxides which are prejudicial to normal friction. I have no hesitancy in saying that we can return to bronze, the same as on the old gun, with a steel ring around it to maintain a very tight contact with the tube. I would advise also making about three grooves on the inner periphery of the bronze piece to allow for the passage of any grit or dust. The old system works pretty well, and we would do well to emulate it. I went to hiduminium to eliminate the operations of steel ring and the assembling of the same. It doesn't seem to work out so that's that. I am surprised that Marquet thought the forward end of the link should be in contact with cam on breech block. If this were the case, the unlocking would start at the time of the highest pressures and might possibly damage the locking surfaces or the link. I have Side. a feeling that the 4 mm. wire recoil spring may be slightly on the What would your calculations indicate for a wire of about 4.1 mm? weak Would
