[Boatanchors] Looking for Mystery Collins Transformer Specs

I saw a homemade power supply at an estate sale having a huge Collins power transformer. Unfortunately most of the identifying label/decal was missing from the top. Of what appeared to be the part number, only the following was legible:
672 - _ _ 4 - 00
The two missing characters could be '00' or 'C0' or maybe something else. I suppose it could be missing a character on the right side as well.
The transformer is potted with rounded edges, weighs an estimated 25-30 pounds, roughly 6" square footprint and maybe 7" tall. I could not see the number of terminals underneath as there were too many wires and other components present. The two oil capacitors on the chassis were rated at 1000V, so I wonder if this is a plate power transformer.
I looked around the web for 672-004-00 with no luck. Perhaps someone out there can shed some light on this.
Thanks in advance for your help and have a great day.
