Vintage Diamond Wrench made in Duluth, MN. The wrench looks to be in good shape showing minor rust from age. it looks like some one sprayed this with a clear coat. It measures approx 10" long. it has Diamond-Drop Forged Tool-Steel Duluth USA stamped in the wrench, the word diamond is getting hard to read. i am not sure what this is for but it is shaped like an old ford wrench so it must be for a tool kit of some kind
