Unknown transformers

Anyone have any idea what these are ?

Extremely late to the party but yes, PP output transformer and seemingly 7k/5 Ohm. If you have 2 there can be built something glowing.
5 Ohm used to be a standard value for wideband loudspeakers in console radios, TVs etc.

Since these are very allergic to operation without load (one of those often misunderstood items) it may be a good idea to measure them first.
