I saw this on eBay and had to have it. You can go on the Bay and see what I paid for it - I'm not tellin'.
I decided to post this because after searching the forums there is only one post by dimwittedmoose and his was stuck at the time.

Champion Miloset Gap Tool Pat. No. 2439363 Made In U.S.A.

The patent date from DATAMP is April 6, 1948.
The 8 wire sizes are 0.015, 20, 25, 28, 30, 32, 37, 40.

The adjustment tool at the other end is movable. When the collar is retracted the tool can be rotated freely and set in any of four positions. There appears to be four different size adjusters.
