Model Number for CGE Distribution Transformer

[SSLA]

Gentlemen: We have a substation with uses six distribution transformers as bus potential VTs supplying protection, SCADA and revenue metering. The name plates have faded in with time and are nearly illegible. We cannot make out the model number but we can read some data stamped into the metal name plate. Here is what we can read:

mfg: Canadian General Electric
Cat. No: 80021779

We infer they are 150KV BIL and the station prints indicate they are 10kVA, 16800:120/70V.

Would anyone know where we could find the model number?
