I've know the Wards ratchet you have. It's difficult to answer your question though. Looks like the Thorsen somewhat. We know Wards tools and their later Powr Kraft were supplied by just about everyone (Duro/ Indestro, Wright, New Britain, Barcalo, Thorsen, etc.).
Your ratchet also looks like early Truth and OTC as well. It's hard to say who made what for whom. The real truth of the matter is since the beginning, the tool makers and brands have co-mingled with one another. They would supplement their line with a specific item made by someone else.
I've seen New Britain 3/4 ratchets that are identical to Truth (pear heads). Odd to see a NB that isn't recognizable as a NB. Now why would NB outsource? Or did they make Truth? This gets even more confusing looking at the old round head plug ratchets. It could be Truth made the early 3/4 ratchets for NB, even though NB is know to have produced for everyone later.
I don't know. Sorry to get off topic. Can you post a pic?
