Simanco33653 year of manufacturing

Can anyone help me date a Singer sewing machine that I purchased at a garage sale. Under the machine it has Simanco 33653 stamped, on the front of machine it has EC561884. It is electric, but I'm just wondering if it has been converted. The bobbin cover plate is missing so if anyone knows where I can purchase one, that would be good. Cheers Teresa
