Ill see if I can check it out tomorrow. I'm in the middle of a huge garage upheaval/ reorganization but I'm pretty sure I know where it's at.Is the bit grinding plated, or bare steel?
Circle H would be late 30's-mid 40's though right?Fall/Winter '63 shows them, disappears by Spring/Summer '64 (obviously not knurled (H) by that point, just overall).
I understood the C series ratchet came out in '32 & made its last appearance in the '35 Craftsman catalog. Many have referenced BE starting around '31. So, my question is, was BE ratchets out before or at the same time as the C series?Forget who did the deep dive, but it has been "speculated" that the (H) was made at the Kenosha factory from when NB acquired Husky. According to AA, Husky filed for bankruptcy in mid '33, so probably '34 or later for (H). AFAIK, there was not a definitive finding for BE ending before (H) (has been speculated).
My feeling has always been that BE started earlier and maybe Circle H was made right up to the transition but I’ve only based that on my examples rather than research. My BE drag link bit has more of the geometric C rather than the long C.Forget who did the deep dive, but it has been "speculated" that the (H) was made at the Kenosha factory from when NB acquired Husky.

There was definately a short period where there was an overlap but I think it was very short.I understood the C series ratchet came out in '32 & made its last appearance in the '35 Craftsman catalog.

Nice comparison Don. If your BE is recessed, maybe it was just a feature on drag link sockets until you get to the=V= series?Apparently the recessed opening was a feature of Bridgeport made drag link bits. Here is an old picture of two that I had.
I still have the faintly marked bit and it is recessed just like yours as is my smaller BE bit.
All of the other 1/2” drive NB sockets are flat
Although the 1/2” drive Circle H universal is recessed.
All of the early =v= drag link bits I checked are recessed as are the sockets

I will do that once I clean it up. My wife has an old mineral oil lamp so I’ve got some on handSmoke, Hit that spinner handle with mineral oil it's magic!
Here are the logos...I just purchased two 3/8 Circle H ratchets. There are differences in the two. One being the small logo above the word forged.




Here's a pic of my New Britain made Craftsman circle H 1/2" ratchet. It also has the "S" stamping. It looks like the S has a "D" & "F" stamped inside of it. No doubt "Drop Forge." Would be neat to know who the S foundry is?I am moving a Circle-H question from a solo query thread by a new 2-post member here to the Long C thread where it belongs, because it's interesting, because it could lead to more discussion, and because I intent to answer it, but refuse to contribute to yet another splinter thread we won't be able to readily find later.
Here is the question...
Here are the logos...
Here is @four.cycle 's answer on the other thread...
Here is my reply...
That "pretzel logo" is most likely a foundry mark. Many OEM's used local or area foundries for production. Those foundries used their own proprietary markings. That particular "pretzel" foundry mark is well known as being affiliated with NB. It shows up on many NB made Craftsman ratchets. Here are a couple others...
But it also shows up on the rare, stylish NDF- series DOE wrenches. I have a few, but I can't find them. Here is one that @Sam'sAutoParts owns. You can see the "pretzel" foundry mark in the panel near the 25/32" head on the right. Mine are older, not chromed, with even more stylish panels, but have the same mark.
We've discussed it before, but I can't seem to find the previous conversations.
There are other letters and symbols (@Outlaw has a ratchet from the same era with an "S" with a vertical line through it, like an S and I monograph) that I also think are foundry marks on NB tools. Those three "dots" are not uniform, which smacks of PO owners' mark, as 4.c alluded to, but I wouldn't bet against them being a foundry mark in that spot.
Here's my Model 115.6845 - Type CKO - M M4 46 - 5 Amps for comparison.
I envy the blue paint on yours. It matches the underside of the base on mine.
I'm thinking "D 3 1" is either week 3 of April 1941, or week 1 of April 1943.I believe "M" indicates your Manufacture date-- D31 = April 1931.
