Value depends on condition, location, rarity and the current market. Unless it is a super rare model or in pristine condition, it
is most likely worth whatever a common Singer machine of the same era goes for in your area. Where I live, that is anywhere from free up to $100
for common treadles and up to $150 for hand cranks. I will not reply to emails asking what your machine is worth.
