I have come up with these two transformers at a hamfest this weekend.

" Transformer" usage? 321475835

This on is the shortest and is marked RCA Transformer, DWG - 114216, Spec - 4243
--------------------------------------------------------------------------------------
This taller one is marked DWG - 112072 Spec - 5287

" Transformer" usage? 321475840

But with only two terminals I would call them a choke.
Any help would be great Thanks

Yes your conclusion looks like its correct. What were you thinking of using them for? Its looks like they could be commercial, rather than out of military equipment. I cannot see the label in detail, but if it were for the military, they might have more than a drawing number, but that's on US military stuff.

Looks like both are pretty hefty and would make for some great door stops. LOL

PS I wouldn't tear those apart, as they probably have PCBs if they are in oil. Usually though, the military had stuff such as oil filled transformers that were solder sealed to prevent leaking that probably isn't the case here, as they also used ceramic insulators under the terminals. since it has a phenolic top, it probably is dry inside.

Did the guy that sold them have any info?

You could test them with an ohmmeter to find out if they are working, unless of course they are shorted. Most transformers would have at least the voltage and/or current, but that's not a rule of thumb.

Thanks for the reply.
Guy at hamfest just shrugged his shoulders.
I thought someone might be able to ID the Drawing numbers from RCA.
Thanks again.
