Transformer ID

[Detroit47]

I bought these 2 transformers at Dayton. They guy claimed they were out of an Alpha. They only have a 120volt primary which I thought was odd for an Alpha.
Has anybody ever heard of a 120 volt Alpha? The voltages looked close to a 76.
Here is what I came up with for voltages.
