During WWII, an adhesive canvas tape was also used to patch small holes about the size of those made by a German Mauser rifle or MG34/42 machinegun on the amphibious trucks used for ferrying troops to shore from larger craft, or for running the wounded back to hospital shop facilities.
The trucks were designated DUKWs, pronounced *Duck* by the GIs. Thus the repair tape was *Duck tape. The GIs found the tape handy for all sorts of other tasks, and a legend was born.
Thanks. Just prove there are as many theories about the origin of adhesive backed waterproof tape as there are about how they built the pyramids.
Maybe that one is the original. Hard to tell. Could be they both happened about the same time.
Do you know why they called it FRICTION TAPE ?
