Disregard - I just found the 13/16 at a flea market! I still need the Wards Master ignition wrench posted earlier, if you can help with that.
Recently found 2 affordable wrenches - 3/8 and 1/2. Now the only missing wrench is the 13/16 - # 1167A. I have all others from 1/4 thru 7/8. Once I have thiis set I may shoot for the 15/16 and 1 inch. These wrenches get used in my workshop.
Will trade for other wrenches/tools or send money.
Thanks
Al
The wrench should look like the 1164 in this photo:
