Here is a recently acquired 9/32 4866 along with its 1/4 brother 4766....is right! That was a cobweb clearer!
Nice find. As far as I know, it's the first conventional 9/32-drive socket I have seen with a 48xx series number vs WF- series number. The good thing about it is that it implies others.
UPDATE on Running Empirical Tally of ostensibly commercial (or at least non-WF marked) 9/32-drive tools:
4814 Socket, 7/16", 12-point (Rubicon)
4844 Screwdriver bit 3/16" (Lugz, Rubicon, MR. X)
4845 " 9/32" (")
4846 " 3/8" (")
4860 Short extension, black oxide (MR. X)
4861 Long extension, plated (eBay)
4866 Flex handle, plain steel (Tin Medic via Don)
4885 Sliding Tee, black oxide (MR. X), plated (AA)










I thought I'd share my passion for Duro-Chrome tools and the great variety of socket designs between Duro- Chrome and Duro-Indestro, as you can see in the photo's with the sockets in front of the case. I don't have an older 1/4" ratchet, just the 3/8" and the newer ones.
Thanks for the informative reply and the catalog download, really cool. there were 2 different postings, the 1st was actually the carbon scraper.Actually a carbon scraper, p57. Gasket scraper is the thing above it.

Nice. Those tools would be a welcome addition to this thread.I thought I'd share my passion for Duro-Chrome tools and the great variety of socket designs between Duro- Chrome and Duro-Indestro, as you can see in the photo's with the sockets in front of the case.

Your carbon scraper was made in 1934 or earlier. After that the round O’s became the shape of plumb bobs.I've had this for a couple of years now, and I thought I'd post it because it seems to be pretty rare. It's a Gasket Scraper circa 1937. It still needs some cleaning. I never would have guessed what it was, and had to Google it . There was a couple of them that sold on Wort Point, but I'm not a member. I just saw it on a Plumb tool thread, but it wasn't this one.












I didn’t see that size of center punch in the Plomb catalog
