Help identifying a delco remy distributor

[Blake Starkenburg]

Found a distributor amongst my clutter of stuff but I am not sure what it fits. I know its early gm due to the lube cap and vacum advance. The tag reads:

1110932 DELCO REMY 9 K 20

Any ideas as too the application or motor it may fit?

1110932: 1959-1960-1961 Cadillac single carb engines.

Cross-checked to '65 and 62-up use a different number.
