MPat, I have the screws for the magazine, It's a slotted flat head #5-48, measuring a few they are between 0.235 & 0.240 long. Length is critical since the hole in counter bored for a spacer which leave few threads and the screw head must be fully recessed or it will interfere with the inner magazine tube. It also required a spacer between the barrel and magazine tube. The spacer is also a special piece turned to fit in a counter bore in barrel & counter sunk to take the tapered extrusion on the magazine tube. The spacer can be replaced with a couple very small lock washers.
The special high collar washer shown work for spacers and also as replacement for the lock washer under the forearm screws, standard washer have to large an outer diameter to fit in the hole. Early 29 used two different length screws for the forearm, both with lock washers, later they used two of the long screws and put a spacer in with the lock washer on one side, two of these lock washers work in place of the spacer and single washer. These were found at Menard's after trying a number of different washers including grinding down the OD on standard #10 lock washers.
PS I also have quite a few of the ball bearing from replacing them with new in a bike, If you need a used ball bearing for a bike they're 3 cents a piece, if you need a cartridge stop the same ones are 3 dollars apiece....... like Numrich....
