A quick day trip to Illinois and back yesterday to pick-up some auction winnings and mixed in were some Ford Dealer service tools. The 5Z-445 band clamp and the 5Z-591 TT rear axle nut wrench are easy enough but the socket wrench has me stumped. The wrench is 22" long and has a 2" socket and is clearly marked with the Ford script and 5Z-1580. I don't think that it is T, any guess or information (Lincoln)?
A lot of Model A stuff and a lot of KR Wilson tooling as well. Not much Model T at all.
Page 4 of this link shows that L wrench in the Sept 1927 Service Bulletin,
as *5Z-1580 1 5/8" L Wrench, the * indicated the tool is in the Fordson price list, so likely for the Fordson.
Thank you for the link. The picture is right and the number is right, but why the difference in the size? The description in the Service Bulletin lists the 5Z-1580 as being an L wrench with a size of 1-5/8" and this one is clearly a 2" socket.
