That's weird. It looks like one is 14mm and the other is 12mm, however the part number only differs by the last letter (and of course the FDP). I think that could be a defective Williams/Bahco based on the shape of the beam. I have this suspicion that the Williams/Bahco combos are precursors to the Snap on wrenches. Maybe it was mistakenly stamped with the Snap on logo instead.
Thats just not right. Its like dragging a steak in front of the dog. Here I am thinking its a new series of wrenches! You get us all excited and then crush us. Its an emotional roller coaster.: You have ruined my whole day.:
Odd thing is that OEXM120B is a valid Snappy part number for an actual wrench. Alright, everyone else who Googled it or looked it up on Snappy's web site, raise your hand =P
