^ Those three all being reversible models causes me to wonder if the earlier non-reversible 3202 model (or its Duro equivalent) was the only one with the 16-tooth action that Alloy-Artifacts.org makes reference to.
I think that Username just picked up one of the Duro Chrome branded models of that ratchet. Unfortunately, I traded away my unbranded one recently with some others. Maybe he can be persuaded to show us an image and count the teeth.

Most examples of the 1/2" drive ratchet shown have the "BS" forge mark. We have yet to identify that drop forger so if anyone has thoughts on who that might represent, please share.


Yup, I agree. I posted it how it came though. Without a model number stamp I doubt Bonney though. I think I remember the 3rd one down had a model number.......3214?From post #51, I marked up one of the drive plugs in the attached image. Not your typical Duro Metal drive plug. The domed shape looks more like a Bonney drive plug. What do you think?
I'm not sure but I'll get back to them tomorrow.twertsy:
The bottom ratchet in post #52 with the depressed panel on the shank: is that a model 3201?
If so, that is the first one I've seen with that handle design.
The drive plug for the 1/2" drive ratchet with the knurled "mushroom" head was a 3215 Indestro. Not sure what the Duro Chrome part number was.
The stamped steel hex drive models shown in post #49 were still in production at least until 1959, as they appear in that year's catalog in the #1454 and #1454MM kits that came in the stamped steel wall-hanging holder.
I'll have to revise that list I made in the "Duro Ratchet" thread and include those earlier models.
Awesome. That's the style in the '31 catalog I was referring to.Since you mentioned Truth ratchets...I've looked for a while and haven't seen one like this. My mom actually bought it for me at a flea market because she thought it looked cool.
1/2 drive, push thru plug (non-removeable), 27 teeth, 10-7/8" oal.
One side says -TRUTH-, opposite side TRUTH TOOL CO. MANKATO MINN.

That ratchet is amazing. Thanks for sharing. Being so close to mankato there is next to no truth around here.Since you mentioned Truth ratchets...I've looked for a while and haven't seen one like this. My mom actually bought it for me at a flea market because she thought it looked cool.

These are the earliest Duro / Indestro ratchets as far as I'm aware. The two pressed steel ratchets are examples of those tiny hex drive socket holder sets that Duro and Indestro pumped out to hardware stores everywhere. One is marked and, as with most, the other is not. However, these both came directly out of their clips/holders, both marked Indestro.
Top to Bottom:
- Duro 1/2" drive Model 672 "Patent Pending" refers to patent #1798481, applied for in 10/28 and awarded 3/31. Thus we date it between those patent dates.
- Indestro 1/2"? hex drive - 30's to at least late 50's (the question mark is because I get .5125 on both openings)
- Last 2 pics are of one I found after the fact. This one is an example of the top Model 672 ratchet but with the patent number, dating it post 1931.
d42jeep said:Here are a couple more Duro and Indestro ratchets. Even though one is 1/4" and the other is 3/8" the heads are the same size and both have 20 teeth.

Damn! Why'd ya have to end that post like that!? TMI in my book[emoji1]List of Indestro ratchets from catalogs I currently have: http://www.garagejournal.com/forum/showthread.php?p=6086056#post6086056
See notes at bottom of that list. That's as close as I can get to a rough guess on dates of manufacture.
The 680 model (post # 66, first photo, bottom) is obviously Duro-Chrome, because Indestro was using a 4-digit part number. Duro-Chrome appears to have used a 3-digit part number for the earlier pressed-flange ratchets (i.e., 677, 678, 680, etc.)
The pear-head models (6072, 6272, and 6472) appear in the 1972 catalog, but I know they were produced prior to that because we had them in the warehouse when I started doing the buying in 1971.
The 2775A appears in the 1982 catalog as a 60-tooth model (with a 6-point "star wheel" selector), but I know they were produced prior to that because we started seeing them in the late 1970s. I never saw (or heard of) a 2875A or a 3275A until I received that 1982 catalog a couple months ago, so it's reasonable to assume the 2775A was introduced first.
After receiving the 1982 catalog and realizing I'd never seen an Indestro catalog with that cover design, I am thinking that we must have dropped Indestro prior to that, but I'm not sure on that one, because I was working in Yelm from 1977-1981 and we had Indestro up there the entire time, and for some time immediately after, because Jim A. (who we promoted to store manager) moved all the tool boards and hung them up above the front counter (instead of hanging on the back wall.)
I am almost certain there was a catalog printed between the 1972 (No. 55) and the 1982 (No. 60) because there were some new items introduced and I ordered new boards for all the stores. Same cover design as the 1972. I had Dan D. haul all the old boards out behind the warehouse and set them alight - there were so many they wouldn't fit into the dumpster.

twertsy said:Note that one of my 3202, female non-reversible ratchets has 18 teeth rather than 16.
Alloy-Artifacts mentions that the first 3202 (non-reversible) model was a 16-tooth mechanism, and then later became an 18-tooth model, and then (finally) a 36-tooth model.
I think I mentioned that in that "Duro Ratchet?" thread when I started making the list of models produced by Indestro.
In your post (#50 in this thread) you described:
"1/2" female drive ratchet Model 3202 - On the face it says "Chicago, U.S.A." above the drive hole, and "Licensed under Pat. No. 1902878." On the reverse it simply has "No. 3202" stamped into the face and "oil" next to the oil hole. 16 teeth
- 1/2" female drive ratchet Model 3202 - On the face it says "Pat. No. 1902878" and "Oil" near the oil hole. (NOTE: see the last two pics -- does anyone else see stamped letters just below the top lip on the handle? - 16 teeth
- 1/2" female drive Indestro-Super ratchet Model 3202 - On the face it says "3202 Indestro-Super" and "Oil" near the oil hole. On the reverse face is stamped "Pat. No. 1902878." 18 teeth."
If AA is correct, if everybody here who owns one of those rolled it around and counted the clicks, we'd come up with a mix of 16, 18, and 36-tooth models (all stamped with the same 3202 model number.)
AA doesn't note what year those changes took place, and only the later (1959, 1972, and 1982) catalogs mention "tooth count".
The original patent application (1902878) filed June 16, 1932, shows a drawing with a gear having 16 teeth. That original patent was granted March 28, 1933.
The re-issued patent (RE19341) granted October 16, 1934, also shows a drawing with a gear having 16 teeth.
Is it reasonable to assume they would have made a new drawing if they had redesigned the mechanism?
So apparently there's an "early" and a "middle" and a "late" version of that model number, but it doesn't look like there's any way to determine exactly what the cut-off points were with the available resources.
