I have acquired a Singer 206K25. I looked up the Serial #EH148517 and saw that it was made in 1952 after March of which there were 1000 made. I was given it by a gentleman that just didn't want it anymore. It is in really pretty good shape for a machine that old. I am trying to decide if I want to keep it or sell it but I have no idea what they are worth in todays market. I would like to keep it but, I'm not sure if I will have the room for it after we move next year. I was hoping that someone could give me an idea of what it is worth. By the way I really do love this site. Anything you want to know you can find out on here. Thank Heavens for smart, smart women.
