Saw an old plow wrench over the weekend in an antique shop. Two actually. One with the Ford logo and the other was plain. The plain wrench only had the numbers 3 and 6, with no lines and no logo. Since I already have one, I didn't pick them up. But after checking on Ebay, I may go back and get them.

If I recall, the price on the plain wrench was 6.50 and the Ford wrench was 12.50. Not to bad for the money. When would the plain wrench have been used in comparison to the other marked wrenches?

From what Ive read from Tim Daley's post down below the unmarked ones were used early on. That would make sense because I believe my unmarked plow wrench came with my grandfathers 1940 9n. I think mine has M and than a casting code on it. Im not around it to look at it. There is a website (not Marvin Baumanns) that says that the unmarked wrench's absolutely did not come with the tractors. I really dont think this is true and statements like that never make sense to me. Anyone who thinks anything to do with these tractors is set in stone doesnt have a lot of experience with them.

Hi Jonas-
The unmarked (no logo) -17014 plow wrench or the "generic" versions were probably made by MANZEL and MOORE and sold to retailers like Sears and Monkey Wards. Moore made CRAFTSMAN tools at one time and eventually was sold to Danaher; then Easton. I would tend to agree with Mr. Harry Kidd that an unmarked version is not a Ford issued tool. I simply say that because Ford was meticulous about putting part numbers on everything. In my collection I have some unmarked with no markings at all; M (MANZEL) logo; (M) MOORE logo but no lot number; and (M)Moore with a lot number but no FORD script. The one common denominator is the exact shape, size and pronounced inch hash marks with the 3 and 6 defined. Harry and I are still researching this as well as the other tractor tools. My recent discovery is that the early 9N tool list has the two small open end wrenches as B-17015 and B-17016. These are identical in size and shape to the A-17015 and A-17016 wrenches issued with the Model A. My understanding is that Ford changed part numbers with a prefix or suffix to denote an engineering change of some sort. I can't figure out what the changes were because like I said they look identical. Of course a little later on Ford went to the O1A-17015 and O1A-17016 wrenches for the tractor tools which were visibly different. We continue to unravel the mysteries, but no one book or document will ever hold ALL of the changes.
