Bob-
I wasn't able to find data on the p/n's you listed, however about 15 minutes with Google came up with the following data on some other Argonne transformers. Perhaps the data might help out someone else someday.
P/N Z (pri to sec)
AR-107 15K to 200 ohms
AR-109 10K to 2K ct
AR-114 2.5K to 11 ohms
AR-119 500 ct to 3.2 ohms
AR-120 400 ct to 11 ohms
AR-504 100 to 200 ct
