Chuck,
I think you are right on the cabinet, at least it is certainly a Victrola cabinet. I also have the mirror. The guts were discarded a long time ago, when Grandpa(Les Flory) turned the cabinet into a hi-fi cabinet with Garrard turntable, tuner and amp, and record storage. That is how I am using it now, but hope to drop a round-tube chassis in there someday and recreate the look and feel of the original set. Vertical hold on the front makes riding sync easier. I may have the original tone arm and reproducer from the phonograph.
