Extremely Rare 1902 Watling Penny Guesser Scale For Sale

Watling Penny Guesser 1902. Condition is Used. Local pickup only.Was actually a nickel back in the day, if you guessed your weight right an electrical connection was made between scale tip and guesser tip (large auto sized batteries were stored in the bottom) and a coin diverter sent it down a return chute to a cup. At some point the original owner removed the return cup and put a cover with his initial over instead. I had another correct cup recasted (pic), in brass and need to either find an original return chute or have one fabricated (its a simple chute about 10 inches long). This scale has original decal on how to maintain on the back of the inside (it has some slight damage) this scale was also used in a 1980s scale book as example of this model, bonus points and $30 to anyone who can send me a pic of it . Less than a dozen known to exist. None with original label.
Update this item is in Round Hill VA with the return mech being fixed by Jeff Stork item can still be purchased but local pick up would be from here.
