Vintage Large/Heavy Unbranded Tube Amp Power or Output Transformer?--*UNTESTED*

Description

This is a vintage piece that I found when cleaning out my parents' home--must be 50-60+ years old.  I can find no branding or other identifiers and am uncertain of what it actually is...possibly a power transformer, or output transformer orr something else.  You can see the measurements via the pics--the piece is heavy and weighs just under 8 pounds.  This piece has NOT been tested.
Looking for someone who has a use for this--and/or can identify for me what it is.
Please review pics closely--contact me with questions.
NOTE: ** Only shipped within the U.S.A. **
