has 5/8" at 1 end and 5/8" and 7/16" at the other end, anyone know what this is for, Bob
Many early tractors had that type in their tool box, when I was a kid I drove a 1950 model JD and it had several wrenches like that in the tool box.
I have several like that. They were sold in the days before ratchets became available, and continued to be sold afterwards too. Some of the ones I have are marked Herbrand, others K-D, some unmarked.
That looks like a Blackhawk tool. If you clean it real good with a wire brush, you may see a name somewhere. But other companies also made a similar wrench Here is a link to a interesting read about Blackhawk tools. They were a major tool supplier during the T era ... scroll down and this tool is shown...
The tool could also be a Waldren Worcester tool. A lot of the early tools look alike...

Here is the Waldren Worcester companion link shown in the Blackhawk link that I posted above. Waldren has basically the same wrench. It is listed as Model T head bolt and several other bolts. They show it in an ad in the link. It is about the 4th photo in the Waldren story. It was to small a pic to copy and get any quality. Both companies were major suppliers of aftermarket tools for the Model Ts.
Thank you, now that is pretty cool wrench, if any one wants one I will list on classifieds soon as I found quite a few, Bob
