1909 Case Thresher

Ok, so I am helping out a non profit with a little R&R to their thresher. The grain tube that empties out to the sacking station has seen better days and needs to be replaced. I see there are 2 saddles and was wondering if they held the pipe together (ie it was built in 3 sections) or if they were there just to help the rigidity of the pipe. 2nd question (long stretch I know) does anybody have any NOS parts? I would love to just put it back with new parts. 3rd - Any idea what thickness the metal was? When I took a caliper to it I got like .048, but that could easily be from the grain wearing it down. Would it hurt to go to a .0625 or even slightly thicker? The auger seems to be a little closer to about 5.25 in diameter, so I should have plenty of available room, but don't want to overload the rod that supports it. 4th - anybody have a parts manual for it that might show what size rivets were originally used? I measure a 1/2" peened over part, but that doesn't necessrily dictate the exact size of the rivet. Lastly, anybody know the ID or the OD? I measured 19.25" around with a string, but what I didn't think about is that it included the seam where the two pieces are crimped together and being an hour plus away I can't just be bop on down and remeasure and exclude the bump. Lastly (I know it is a second lastly) does the discharge end get smaller or can I not measure. I took a tape to it and it seemed like it was more like 5 5/8" in diameter, but when I calculate the diameter off the circumferance I get about 6.13 versus 5.675 with a tape.

Pics are of the entire tube, the auger output (where I seem to get a different measurement) and the SN.

Thanks.

From the serial number the thresher is a 1948. Early threshers were galvanized steel and later ones were painted flambeau. I have about 8 Case threshers. I have replaced the auger tube with 6" aluminum irrigation pipe, never rot again. Threshed with one of mine last fall...

The band where it sits in the carrier is there to keep the tube from bending when in the "home" position. The tube and auger is same size from one end to there other. I used bolts instead of rivets to attach the tube to the cast housing. Easier than trying to rivet in the housing.
 
The saddles are support the tube during transport. Early threshing machine had steel wheels that shook up the machine when moved. The late models with rubber tires were a bit smoother, but the machine design didn't change.

After the thresher was positioned and staked down, the grain auger and blower were rotated out into working position during the actual threshing. Before the machine was moved again, the auger and blowers were rotated back and lowered onto the saddles for the move.
