The transformer in question was used in the well known Ortofon T-30. It is a two channel device with selectable inputs for 3,6,12,24,and 48 ohm impedances.
The connections are as follows: left input= green/black, right input= red/black, left output=green/blue, right output=red/blue.
I'd say you have a keeper.
Hope this helps.
