P&C also made open gear ratchets. Very similar to the Thorsen ones, for reasons of history! (Thorsen was founded by ex-P&C employees, but I think they developed the open gear ratchet. Someone will chime in with more infor I am sure.)
Post 846 in this thread and for background, posts 500 and 501 of the "post up your Thorsen Tools!" thread.
MR. X's excellent catalog timeline analysis shows that Thorsen made an open-gear ratchet first (at least as early as 1934..., with P&C following suit sometime after 1936 and at least as early as 1939), but that doesn't explain why P&C's open-gear rat looks so similar, near-identical, if not exactly identical. After all, many other mfgr's were making open-gear ratchets for many, many years. They don't all look like Thorsen's. So why would P&C's look like a Thorsen knock-off? Beemer alludes to the answer. I have pointed it out before. Peter Mortensen. He was the tool-and-die guy who left P&C with Ned Boyd to form Thorsen in 1929 - and the only guy who went back to P&C some time in the 30's. I think he took the design he originated at Thorsen back to P&C.
There are other P&C/Thorsen similarities. The use of the "MFD." marking, as an abbreviation for "Manufactured", for example. Sure, Plomb used it too, but only after they had acquired P&C, raising the distinct possibility that it could've been a convention Plomb picked up from P&C. What is the
only other company I can find who used the
exact same abbreviation (not just "MFD", but "MFD
.") on their products? That's right: Thorsen (and Thorsen spin-offs Giller and Dayton). That
can just be a coincidence, I suppose. But it's awful curious with a lead tool-and-die working for both outfits.
In that 3rd photo of the brochure just to the left of where it says "handy pocket catalog" on the bottom of the cover page looks like one of those "litho in u.s.a." with the 4 digit stamp. Can't make it out though.......Brian, little help?
Good catch. Near that is a pre-Zip Code postal code address, too. So, before 1963.
