CMARAS1234

I dont know what i have,, but it is as small as a featherweight but weighs about 50 pds. no attachments. but does have bobbin and needle plus the old light with the big bulb. The machine is still in my car as it weighs so much I need someone to carry it for me. (due to shoulder surgery) so no picture yet. also the serial number is strange It is a large EL then a very very small 89 then a regular size 1066 and then a small separate oval seal lower down that says 99k . Any one have any knowledge on this machine. I could not turn it on as the foot pedal has something loose inside ,and I am going to let Grandson look at it and it needs a belt. It is definatly a singer and the decals are in excellent shape. any Help would be appreciated. cmaras1234 PS............. I always though the 99 was a big machine that had a kneebar and a coffin top case???? With a skeleton key. i have 2 in my shed.
