[AMRadio] Thordarson Transformer ID

I have a very large high voltage Thordarson transformer that appears to be a PUV type.  There are no identification labels, etc. but the original owner did identify it as a Thordarson.

The end bells have slotted "handles" to move the transformer around.  Never have seen this before.

The high voltage connectors are very unusual in that they are meant to be used with plug type connectors that slip into the white porcellin insulators.

There are 10 of these, with five in a row vertically.   I suspect that this transformer was manufactured in the 1950's or so.

The primary side has four terminals.  The original owner told me that it was for 120 volts AC.

Can anyone help in identifying this unit.

Thank you.
