I would like to add a word of warning when dealing with old transformers:
The 'newest' post-war transformer is now at least 54 years old. It is an extremely dangerous practice to operate ANY older transformer WITHOUT replacing the 110V AC power cord. This is not only a fire hazard, but the risk of potentially fatal electric shock with an old, frayed or brittle cord is drastically increased and not something to be easily dismissed.
If you don't have the necessary skills to replace the cord, have a pro do it. But don't ever operate an old transformer with an original cord even if the cord looks 'okay'.
