Also it looks like the serial number would be more likely at the beginning years maybe mid to late 1960s. If there is a model number there maybe at the bottom or side of stitch length than you can try

http://www.singer.com/ is the global site, and evidently has a choice for Asian sites.
I'm thinking that the cover for the cams is under the spool pin on the front of the arm?
