Let me see if I can help you out here. Your machine Singer Treadle, "AB Series", Model No. 66. Made in Elizabeth, NJ, USA. circa 1927 No. Alotted: 50,000. In Oak Cabinet , with the gold decals on Machine . You have one of 50,000 made of this model. The model 66 had been in production since 1900, and finally finished in the 1950's. It is made of cast iron. The very sturdiness of the machine make it a veritable workhorse, able to sew the finest organdie baby gowns as well as through leather and canvas.
They are currently valued on the retail market ( cost replacement ) for an average of 550.00-600.00, depending on where they are for sale at. Unless you just have to sell this, I would not do so right now, the market is low, due to the poor economy and so many individuals are selling so low it is depressing the market. I would hang onto this awhile and then sell it when the economy picks up some. It will do best sold privately such as list it on Craigslist for free where the buyer picks it up. Or consign this in an Antique Shop where they have good traffic. Do not list it on Ebay unless you are willing to sell it very low. There are collectors of Singer Sewing Machines, and if the machine is where there is traffic they will find it.
