I am trying to figure out if this is the right generator for my 38. The one I have with the car doesn't have the Delco Remy tag. I know that the two terminals with nuts are connected to wires but what attaches to the screw?
If I'm reading the number on the tag right, it is a 1102667. That generator was used from 1940 to 1948, I believe, and was classed as a type no. 72-U. That number had been superseded by 1102737 by 1954.
An original 1938 generator should be a type no. 60-U. The original generator number would have been a 1100004. The number in the 1954 master parts list was by then listed as 1100502.
If you have a radio a condenser was mounted there with the screw.

You don’t want to run the more modern generator on a 38 regulator. The 38 generator has a third brush that causes the field current to be limited. The 38 regulator does not provide this function.
My 1951 1 Ton is now on the road! My 38 Master 4 Door is also now on the road .
John – Was your car produced in Canada or the USA?
Note that the Delco-Remy tags with “The McKinnon Industries, Limited” along the top and “Made in Canada” under the number section were for assemblies that were made in Canada and installed on Canadian produced vehicles. Many electrical parts (generators, starters and distributors at least) were made in Canada to avoid duties which were imposed if they were imported from another country. The McKinnon tag is correct for Tim’s Canadian car.
For US produced vehicles, the Delco-Remy tag would have “Anderson, Ind” along the top and “Made in USA” under the number section.
Although they were the same functionally, the tag should correspond with the country of assembly.
I was focusing on the stamped number on the tag for John's reference since it wasn't clear in the actual generator picture. I wasn't sure many people would notice McKinnon on there but not much gets by you Tom lol.
The generator / regulator matching can be confusing around these transition years. The main point we've been trying to get across is that both the Generator and "regulator" need to be correctly matched to work together. I struggled to understand this myself, but with the help of a few people more knowledgeable than me on here, I made sense of it so wanted to pass on the correct numbers for 1938. Just don't ask me about 1937 or 1939 as they are different too lol.

Note that ths car is a cabroilet so will not be a Canadian car. It was common for owners to remove the 3 brush generator nd voltage control and replace them with later (incorrect) units.
1100004 was the original part number for a 1938 and 1939 passenger car......1938 and 1939 generators were the same. That will be the number stamped on the tag. There are later replacement numbers that would be considered incorrect. The original 1938 volt. control had 4 wire terminals and the 1939 3. The improved 1939 version replaced the 4 termnal unit as a replacement part in 1939 so the 4 terminal control is very difficult to find
