This 8-inch DOE wrench is stamped Transmission Band toward the 3/4" left open end, and Gasoline Line toward the 11/32" right open end. I cannot decipher the makers mark, but it might be TFC - CFT - TCF ? The wrench is also stamped MADE IN USA.
I don't know whether this was an after-market wrench or an original equipment wrench. Can any of you guys supply more information about this wrench?
