Hi Terry, I also own a Green re-babbitting and boring jig. I will add some photos later. John Green and Sons started in Freeport, Il. they were later purchased by Simplicity Co. of Port Washington, Wi. Siplicity sold other forms of babbitting equipment. Simplicity I believe was later joined with a company in Connecticut called Waterbury. They also sold babbitting equipment and seemed to possibly be merged with Ammco, a company in Chicago, Il. called Automotive Machinery Manufacturing Company. Ammco had also purchased Hempy Cooper of Kansas City, Kansas. Hempy was an early company which made babbitting appliances, connecting rod boring attachments for lathes and many forms of babbitt pouring jigs for rods and cap bearings. Your machine looks like it is missing the fine thread feed nut which allows the fine feed to bore the bearings. I will attach pics if I can of Simplicity equipment if I can.

I have rebuilt approximately 6 1932 Buick (0 series distributors and it is nice to see how some have gone to a 1933 8 lobe cam. I disassembled one distributor which had no centrifugal weights under the main plate. So the car would have had no possible way of advancing the spark. Some weights were found and installed, end of story. Does the 1933 8 lobe distributor have the same advance characteristics as the 4 lobe?

Dual point ignition is supplied for one of two reasons. In the case of your '31 Buick each set of points takes care of 4 of the eight cylinders so there is a longer saturation of the coil takes place increasing the available voltage. Otherwise you would also need an eight lobe cam in the distributor rather than four. Fast forward to the late 1950's Chrysler began using dual point distributors with the effect that each sets of points fire immediately after the first which made the spark DWELL increasing a good spark to plug.

Brandon, I own a 1059 Weidenhoff distributor tester and possess a manual. I can copy and send you one. I believe I can copy it for about $7.00 plus shipping. If interested email me at sponge19501924@yahoo.com with your shipping info. Dan Manola
