Hello, I found this at the local antique store. Owner thinks it is some sort of wrench, and maybe farm related? John Deere green? There is a raised C7 on the casting . Overall length is approx. 12", and the end with the tag measures approx. 1-1/2" x 2". The top part of the end with tag has a 1/4" wide x 1/8" deep groove on both sides, & the lower part has the same groove, but with vertical ribs that look like they would engage a gear? I had this in the What's It Forum, with help from oldgoaly. Cool looking piece!! Regards, Lou
