I have a 306M aka Sophia Loren. She is my favorite sewing machine. Yours is worth fixing and restoring. Even my OSMG did not know of the 306M model. The serial number records were destroyed when the Italian Singer factory closed in about 1967. The only thing that my machine needed other than lots of oil was the motor which had a "squeak" and was fixed by the OSMG. He said that the gears in the motor needed some lube.
