Can anyone ID this wrench? On the back is "N" or possibly z. 8 1/4" long. 31/32 and 27/32
I believe "SP1" is short for "Service Pack 1". It is a remedy you apply to Microsoft Windows operating systems when they don't work correctly. Either end against the PC is fine.
Oh,oh...I applied BFH ..was that the wrong service pack?
Oh, the wrench....
Found other wrenches with SP prefixes associated with Independent Harvesting co, but did not specificlly find a SP1 ....
Perhaps "CTK. MFG. CO. (Chicago Tool Kit Mfg. Co.) / SP1 - - 8.25". (see R1-74)"???????
