You do see the patent document cite an Indestro Catalog No. 20-S that I already alluded to and to which matthew subsequently picked up on as well, right? You seem to be ignoring it. I think that's what the October 25, 1955 date is referring to. Again, it sure looks to me like when Barcalo was submitting their application (Nov. 23, 1955) they cited the most recent they could find. I see that there's a Catalog No. 22 dated 1959 in ITCL. No. 20 (1952), No. 20-S (1955) and No. 22 (1959) seems like a logical sequence to me.

This explanation doesn't call into question the logic of the ad in the 1952 Hardware Age for Indestro Catalog No. 20 confirming that No. 20 was published in 1952.

I was also going to say that given the design patent was only filed one month later than the catalog date, and considering the time it would take to do the research and prepare the filing, I think it would be surprising if the Indestro catalog was actually published Oct/55 and the reference actually made it onto the application (meaning that was just a retrieval date).

But of course that may not have been the case - it may not have been in the initial application, and was added to the patent by the examiner during the approval process. Which would make the October publication date more likely, I think.

Any which way, cat20 = 1952 seems to work.

RE: an Indestro Catalog No. 20-S

yes, I saw it. no, I wasn't ignoring it.
I have not seen or heard of a catalog No. 20-S, and just didn't comment on it.
there are "A" and "M" suffixes used. thus far I haven't seen an "S".

Just to hopefully clarify, 4.c, I wasn't expecting you to comment on it. I was expecting you to acknowledge that a Catalog No. 20-S is also cited in the patent document, that it is cited successively to Catalog No. 20, and that it (not Catalog No. 20) is quite possibly the catalog to which the "October 25, 1955" date is referring. The whole premise of your conclusion that the USPTO is confused or misinformed is your assumption that the date is referring to Catalog No. 20. But if the date refers to No. 20-S it may not be wrong and is not refuting Mark's sleuthing about the date of Catalog No. 20. And again, that interpretation seems even more likely to me because of Mark's sleuthing. It seems much more likely to me that the USPTO has the date right and that it's referring to a Catalog No. 20-S we have no prior knowledge of than the USPTO is referring to Catalog No. 20 and getting the date wrong.

Time and a copy of No. 20-S turning up will tell! :)

Thanks. Some correct pliers for the set arrived today. Too bad eBay sellers own wire wheels!

Yup I hate when sellers wheel the **** out of stuff. I bought a Bonney hacksaw that the dude totally ruined with a wire wheel.

Indestro-made - Western Auto "ChromeXQuality" 1/2" drive SAE socket set

looks to be missing the 7/8" and 1" socket and I'm a bit disinclined to go chase down the drive accessories. box is in decent shape - has the obligatory paint splatters on the top.

Nice wrench. That one is GMTK correct.
So it seems, though many people here know much more than I about such things. Didn't make the connection until you asked. Someone at G503 included a Duro in their Mechanic's set. I'll accept their opinion and just say, "it's a nice, substantial wrench."

Another thread I fell off for several weeks...

Fools and wire wheels... Years ago I took a small back saw to be sharpened, (they did not have saw set fine enough so all they could do was the grinding...) and it had a brass back. the idiot "polished" the brass with a heavy wire wheel -obliterated the markings... I was so upset...


I picked up this DOE Duro Chrome today. 1/2 - 19/32. on clean up I noticed a G in the code No? G1025 - War years? G for "Gov"? :dunno:

Probably been discussed and I just CRS...

It is generally accepted that tools with a part number starting with G were made in 1945. Although wartIme, G tools don’t have the Circle DC (X) marking.

Here, for anyone who wants to see it. It has a cover for the open ratchet, and it is here somewhere, but in use I found it to be a nuisance, so took it off. It just presses on.

Just a teaser, I have a lot more.
There is an active Barcalo thread where you might like to post your nice Barcalo wrenches.

Are all of these DURO? dr1.JPGdr2e.JPGdr3e.JPGdr4e.JPG
They are all 1/2 hex drive sockets except the top one.
The top one is 1/2 square drive, marked 11/16 with stars on both sides. It is for 11/16 square nuts I believe, either that or some kind of 1/2 square to 11/16 square adapter.
The largest one is a one inch with no markings on the socket, just knurling. also 1/2 hex drive.

Alloy Artifacts does a decent job on the ID of early Duro and Indestro sockets. The star and trapezoid marked sockets are very likely Duro or Indestro, the rest I’m not sure about. I’m not too strong on hex drive tools.

^ looks like Duro/Indestro to me.

The 3/4" socket marked " 3/4 " (with no other visible markings) is somewhat puzzling. No stars or trapezoids on that one?

Nothing else on the one marked 3/4.
The knurling width by eyeball looks the same as the 1/2 with the trapezoids but may just be a pretty much standard width for a lot of socket companies.
These were all together in the same box. Along with a 3/8 plug Duro-Chrome 4488 non reversing CUB ratchet.

Duro/Indestro seemed to be a bit confused about markings - sizes were expressed " 3-4 " and " 3/4 ", some were marked with stars, some were marked with trapezoids.
It might be less confusing if New Britain hadn't been making sockets that looked almost identical.
The "all together in the same box" has to be given some weight - generally speaking, people don't go out of their way to mix up brands of product in tool sets. We can never know what the previous owner may or may not have done, but it's reasonable to assume that everything in the box was the same brand when it was purchased new.

A nice mix of wartime Duro from the flea today.
G2013A DBE, 721 DOE, 1A tappet and 11/16 socket.
