    I would not buy it if it looked like that.

    The housing of the distributor in question has definitely been worked over - as already pointed out, it should have the machining marks visible. That would be enough for me to not do the deal as there will always be a giant question mark hanging over that distributor.

    Well, after looking it over, dimensions appear to be Machined identical size to the known Original 112168 distributor I pulled out of this car. It has the correct vacuum can as well as the 530ccw shaft. It does appear that them stamping impression is more pronounced at the beginning and end which I would think would Be Opposite if it was an attempted flat stamp. Also there are some marks from the tooling but pretty faint. Some remnants of yellow paint are on the base too. Here are the dimensions of both using my starrett outside micrometer. Give me your thoughts please especially regarding the diameters I found.

    1112168. 3.812” stamping area diameter
    3.798” cap mounting diameter
    1112019. 3.812” stamping area diameter
    3.796” cap mounting diameter.

    Do we by chance know how many places were producing these distributors for GM in that era?
    Wondering if there were multiple factories that may have had slightly different manufacturing processes or fonts etc.?

    Here is 3 more . I can’t say they are restamped, but it’s funny they all have the same date and quite different condition. 16CE4FC5-B8D8-425B-8983-E5A0FC3EC455.jpeg C184DA3D-9322-41D1-9A74-2555D9DDE51A.jpeg 4993209C-8C28-40EE-80D2-F4A41284A0AA.jpeg

    I’m going to surmise that these were some one off run of parts then. There is zero evidence it was turned As it’s .004” variation In diameter and stampings were more than .002” deep. Either someone bought new unstamped items years ago For resale (unlikely as they had little value back then) or they made A small Batch run for some reason at the factory the following day (Possibly some rejects were found in the machining operation On day 1 so they had to adjust and Run additional parts the following day to cover those rejects. This one is in good shape otherwise so I’ll go ahead and rebuild it. Thanks to all here for your help and Comments . It’s invaluable!.
