Well, did some investigation this afternoon. A 1950 Delco distributor(model 1110811 9K20) has a grease cup on the side, a 51 doesn't. The 50 vacuum advance is a model 1116041, with the number 344 stamped on the arm. The 51 is a 1116060, with the number 158 stamped on the arm. The earlier model also has a right angle brass fitting on it. The fitting has restrictive ports in it. On the 51 version, the restrictions are in the body, and isn't a right angle. End of story, have to get a new/rebuilt one before the old girl will run right.

I did run a vacuum test on it again, using a hand pump. Absolutely dead.
