It does have a reflective back. I see the reflection of your hands.

Yeah i know....i said the OTHERS i found do NOT have that.

The lock does not look like it belongs to me.....and of course the design is very unusual as you say.
How big are the bottles? Could it possible be a cave a liquor with the glasses missing and the lock replaced?

Bottles are estimated 8 1/2" (h), 2 1/2" x 2 1/2

Its possible it could be a cave a liquor. Mine appears to be used to Hang on the wall and or sit upon a table.

That lock appears to be an ordinary modern, low cost, padlock. Not enough detail to tell. Its possible the original did not have a lock, but had provision for the owner to add his own lock as desired. From a design viwepoint, an original lock would have had a brass colored body to match the other brass parts.
