I do offer phone assistance for the first week after delivery should you have trouble operating any machine you purchase from me. The vast % of problems are due to dust/lint and lack of lubrication. Most of the time, when a machine has an issue, it is not broken, but in need of an adjustment or basic maintenance. However, since some of them are close to 65 years old, there is no specific warranty offered. It is hard to believe the quality that went into them. GUARANTEE: These machines were designed in a time when things were made to be maintained and repaired not tossed into the dump. Please ask any questions you might have about any machine you may wish to purchase from me. Included will be fabric sewing samples so you can see the stitch quality for these amazingly durable machines. I have documented the work I’ve performed on my main blog page with photos so you can see what goes into getting a machine ready to perform well again. Quite a few hours have gone into all of them to get them ready to sew. Others needed certain item replaced such as belts or drip pads etc. Most of these were not broken, but simply in need of TLC and cleaning/lubrication. Each machine for sale here will have a list of things I updated/repaired. I think its important to list out what kind of service a machine has had so you can get a clear idea of its running condition. Some sellers list their machines as “serviced” without being very specific. ABOUT THE MACHINES: The machines on this page have been serviced and refurbished.
