Antique Detroit Automatic Butchers Scale No 50 Stimpson 1845-1912 (JP) For Sale

This scale came from a high endantique house. The owner is liquidating. Please read and feel free to ask me any questions. I did some research and I put the possible span of manufacture in the listing based on what I found. I found a similar scale to this one in abrochure online from 1845. I do not know if this is the exact one. I found a court document where the Stimpson co sold out and the document read that the Stimpson name was to remain on the scales being manufactureduntil 1912. Thats all I know and I realize this is somewhat vague. I am not an expert. If there are any experts out there please feel free to correct any information I may have wrong. I do know this is a rare find and if there are more out there they are in private collections. I could not find one of these anywhere online for sale. It does work, the hooks are in great condition, both on top and on the bottom. The glass windows are not cracked. The numbers on the back long windows have some rust but are legible. I have started this low and there is areserve to protect the owner.
