I found info on my Model 15, 1918 also made in Elizabethport Factory, New Jersey. You can find more, including how to purchase the manuals (approx. $15). Google or GoodSearch under "Ehow.com" and also Singerco.com and Ismacs.net Do not oil without the manual. The websites show guides for manufactured dates and mechanics in your area. I had the best help in restoring mine with the help of a Singer technician.
