T-1917 wrench

[beast_3]

I have a T-1917 Ford wrench that fits a 11/16" nut on one end & the other is just a tiny bit smaller, like maybe it had been 'pinched' smaller.
Anyone know what size it should be? I've heard it's for adjusting transmission bands.
Thanks!

Probably 21/32". That was a fairly common size some years back, as were other /32" sizes.

One end is for use on the band adjusting nut, the other 5/8th, which is a common size on the Model T. I would have to find one to check. I use modern tools on my T's so don't have one handy. The No. 1917 wrench came with every car tool kit so are very common, think 15,000,000+ made. 5/8th is kinda strange. The only bolt heads it might/would fit is the retainer on the timer and water inlet/outlet. Most all the rest of the nuts and bolts take a 9/16". The only other wrench that came in the tool roll was the adjustable.
