I thought this may be of interest.

Grafe Auction

 

I didn't see a search function, which would be nice so I could just look for 40-41 truck stuff.

 

From the website: "Parts Inventory, Part I, October 11, 2016. Beginning at 4:30pm, we will sell 762 lots of parts via online only auction. These parts are located on the first floor of the Litle Dearborn building. You may browse and bid in the Parts Inventory, Part I catalog at your leisure. Remember the first lot sells at 4:30pm Central on October 11, 2016."

Click on the underlined section in the website listing for the inventory. The search catalog window is just below the CATALOG tab. I entered 1940 and got dedicated listings.

Now to find someone local who would ship your/my lot.

 

Try "53 tonner" over in the 48 to 56 forum. Sounds like he is near Little Dearborn.

I tried that on 1940 and 1941, both showed no matches found
