Hello my name is***** am one of the expert appraisers here at justanswer. I would be happy ot help you. The singer 15-91 sewing machine American Made was produced in 1948 and even today is a top machine to use. They say it is better to buy these, fix them and use them. If the machine is in great working order and the cabinet is also in great condition the value is $350.00. The hard part is finding the buyer that would pay top dollar for the machine. Realistically these machines are selling for 175-200 on the secondary market. If I may be of further service please let me know.
Please rate my answer when you have a chance as this is how I am paid on the site. Thank you again for sharing your machine .
