I too, have a Maybe Hot Nut Vendor.
Mine is the 1931 / 1932, aluminium version.
It is in
near perfect condition.
I don't have the original red glass lens, mine is plastic
and I don't have the original globe hold down, and the correct light socket.
Plus, there wasn't a decal attached.
It does have the heaters and they work.
It is in excellent shape and works correctly.
I have included a picture of mine
and a patent for yours.
Upon looking at my vendor, I noticed that it doesn't display well, you can't see the Dixie cup vendor!!
I can re-post with another picture if wanted.
I count this vendor as one of my more unique vendors.
