Brad found it in his dad's tool box, in Australia, and wonders if anyone can give hime more information about it... like what the 1 and 2 nut or bolt were found on the Model T, and if the wrench is a winning lotto ticket if he sells it. Heck, I'd like to know that too!
Steve emailed me to let us know:According to the forum at http://tinyurl.com/437zenl there were 3 styles of the T-1917 double end wrench. All were 5/8" by 11/16"
They sell everywhere from $5 to $10.
