Answers:
According to the Singer site (http://www.singerco.com/support/serial_2...
Your machine is a Model 99 built in 1934. A 99 is a 3/4 size version of the Model 66. It will take low-shank accessories (the most common kind) and 15X1 needles (also common, get at any fabric store or even walmart). It only does a straight stitch.
You can download a free copy of the manual from Singer here: http://www.parts.singerco.com/ipsvcmanua...

Your machine will be easy to service and maintain yourself. Be sure to throughly check the electrical wiring before pluging in and using. If you want more information and advice, join the Yahoo group "Vintagesingers". Have Fun!
