I just got this one in the mail yesterday. It popped up on eBay and I had to grab it. Sorry if I bid against any of you. I paid more than I should have but I haven’t seen this set before. It’s a 40-piece set that goes all the way up to 3/4- inch but does not have the machine screw sizes. The part number is 9-5212 and doesn’t show up in any of the catalogs I have (and that’s a lot). There is a 9-5212C that shows up in 1969 but it is a 59-piece set that includes the machine screw sizes and easy-outs. I think this set is older than that. Here is my logic. Inside the lid of every Craftsman tap and/or die set, they have all the Craftsman tap and die sizes listed on a chart with the tap drill sizes. Even for the sizes that are not included in the set. The set I just got has that chart inside the lid as usual. The machine screw sizes are listed even though this set doesn’t include them. The smallest size listed is #4-36. Craftsman stopped using the 4-36 in 1962 and all tap and die sets from 1963 and after, came with a #4-40. The die stocks have the sliding “fingers” on the guide instead of the pivoting “fingers” that were also introduced in 1963. My best guess is that this was sold in stores, or by some other professional channel, somewhere between 1959 and 1962. This set is in excellent condition. The only evidence of use is circular scratch on the large die stock. The tap wrenches were still gunked up with cosmoline and took some effort to get them moving again. If anyone has any information on this 5212 set, please let me know.
