Title: GM 18 wrench
Post by: jimwrench on December 15, 2012, 12:16:27 PM

 I have a GM18 wrench that I think is an orphan. There is one on e-bay listed as a carriage wrench and since you can't lie on the internet I suppose thats what it is. Somehow I still have doubts.

Are the openings by any chance 1/4,3/8,1/2 ?

Thinking more along the lines of a set screw wrench....

Rathbone Volume One page 192 shows this wrench along with a manufacturer's tag labeled "Hand Grist Mill". Someone found the tag and wrench wired to a grist mill. We can only assume that the wrench originally came with the grist mill.

 Whoops missed that page. Just went thru Rathbone looking for another wrench and didn't see that page. Didn't see it in supplement and didn't go page by page looking for the GM18.
