You might want to ask for an appraisal to see what the market looks like just remember, the price an appraiser quotes is for insurance purposes (not usually retail) and for a generic area.The vintage #15-91 is a popular machine that was sold with a motor between 1918-1951 but most of these are not bringing a high price - with or without a cabinet.You should check your local sale sites to see if any of these vintage machines are listed for sale in your city. Most sellers list these machines as pick up only so that basically means your buyer would have to live in your area and some areas will do better with this type of sale than others (no one can predict what your area is like).If the machine is all original and the cabinet is of the same vintage it is possible you could ask $250 - $500 but if you planned on shipping the shipping would possibly cost a buyer $85-$100 so that puts a damper on selling for that price.The 31-19 machine was built between 1914 - 1946 but I did not think it had a motor? Perhaps I am thinking of another machine.
