A friend happened to have these transformers, so he and I worked a trade. They are both Chicago Trans. Co., but I can't find them in any of the online catalog files. They are possibly ones that were rolled for a specific Mfg.

The first one is a driver xfrmr # 14424. It doesn't have a terminal pinout diagram on it (8 lugs). Turns ratio is Pri-Sec - 2.5:1.

The second has some surface rust imparing reading the info on the side. I can make out the part# 55C202. It also says 250W, 250mA, and 7000v test.

Does anyone have complete info on these?

55C202 could be a manufacturers part number. Military or Hallicrafters?

I was thinking along those lines. I wonder if these could be from a BC-610?

It sounds like a BC-610 transformer. If you could post a picture of it, someone might recognize it.

O.K., got to a good point where I could take a couple of pictures. Not the best at photography though.

I know that this is an old post but it is a BC-610 modulation transformer. I have one with the same exact numbers and it will do the job.
