Hello, All. One of the reasons that I bought this is that no one in the store, (myself included ),knew what to call it, just had "old tool" on the tag.Overall length is 27-3/4", the length from the top of the socket to the end of the steel is 7-7/8". The flat piece is 1-1/8" wide, 3-1/2" long, and is 3/8" thick. No visible markings, handle diameter is 1-1/2" . Thanks, Lou
