Leon is right. There are lots of machines out there. Most are not very valuable. If it is in pristine condition and in working order, there might be a market for it. If someone's grandmother had one like it, or it has some special feature, it might be desirable.
If I had it, I would do a search on Ebay to see if that model has sold and for what price. Be aware that the only ebay prices that are published are the ones that are sold at auction. The "buy it now" listings are usually negotiated, but the asking price is the only price that is published, not the actual sale price.
Good luck.
