This Rare Vintage Antique Stamp Machine Mad by Schermack, Detroit Michigan is for 3 and 4 cent U.S. stamps. It measures 5 1/8" wide x 5 7/8" deep x 13" tall. The base measures 6 9/16" x 7 5/16". The knobs do pull out and return but I do not know if it is a functional machine or not. It appears there is a piece of the pot metal broken on the inside but the knobs do pull out and return but the one jammed and I had to fiddle with it to get it to return. I don't know if the piece of metal ...where the stamps come out is supposed to be like that. I am not familiar with these machines to know if it is complete or not, I would think it is in need of repair, but a very nice piece for the collection. I have taken many pictures inside and out of this machine for you to determine condition (see images) and for you to make your own evaluation as to the worth. The reason I called this machine rare is the "Shield" that is on it that says Buy Stamps Here. I could only find one on the internet that went at auction and they said it was a "rare" machine with that shield. You collectors will know what you are looking at. I will in no way end this auction early or for a buy it now offer. My starting bid in no way reflects the value of this machine as I would have you collectors determine the value. As Always, No Reserve! Enjoy Bidding!
