I picked up an interesting hex-drive set today, not sure what. I only have a pdf of the 1935 catalog, and there's no large set of hex drive in it, just a bunch of smaller ones. There is a square-drive No1536 36-piece "12 Point" Master Socket Set, and this somewhat resembles it, except these are 6-point / hex-drive.
I'm not sure what to make of the ½" square drive ratchet, plug, and extension. There is no hex/square adapter, so I'm thinking they aren't part of the original set.
6pt: 1-1/4, 1-1/8, 1-1/16, 1, 31/32(x2), 15/16(x2), 7/8(x2), 13/16, 25/32, 3/4, 11/16, 5/8, 9/16, 1/2, 7/16, 3/8, 11/32, 5/16
4pt: 7/8, 11/16, 5/8, 9/16, 1/2, 7/16, ⅜
hex extension / size adapter, (2) hex size adapters
I don't think the short DOEs are Indestro; I don't see any logo, and they are not all of the same style.
