Vintage UTC P-1, Low Impedance to Grid Input / Mixing Transformer, NOS?

Description

For your consideration:  Qty 1 vintage UTC P-1 Low Impedance to Grid input and mixing transformer, as received from an estate.
Transformer is in good mechanical condition with some missing label printing.  Pins are nice and straight.  Not sure if it is NOS, so selling as used to be conservative.
Please refer to the pictures for additional details.
