I would go check it out. Call the seller and ask him for the make and serial number of the sewing machine. If it is a Singer, parts are readily available. Often pictures do not show the true condition of the machine and cabinet. If you don't go just to look at it you might kick yourself later that you didn't. And you may even politely point out to the seller the "issues" with the machine and make a lower offer. Check out the cabinet make sure there are no missing parts or damage to the wood. And do check the treadling mechanism to see if it is complete. Final decision is do you want a project or do you want to sew?
