Can anybody help ID this old potted Hammond Tranny marked 92747?

Been helping a friend organize the estate of her late husband and we have come across some of these Hammond sealed transformers. Marked 92747, has 7 pins, ohm meter gets the following readings:
Pins 1--2 reads 20.6 ohms
Pins 3--4 reads 23.6 ohms
Pins 5--6 reads 1 ohm
Pins 6--7 reads 1 ohm
Pins 5--7 reades 1.8 ohms

Also have found many tech sheets. Here is on for the 800 series transformers. Where would be a good place to upload these to share? Was thinking of the AK database but maybe there is a more appropriate space?
