Trying to fine info on this model #FR2493958, aside from patient dates on the bobbin access plate there are no other numbers.

Trying to find info on this model FR2493958 white rotary sewing machine with automatic lift cabinet. I am in the process of restoring both the machine and the cabinet for my own personal use. While I was disassembling the cabinet to clean and refinish, a spring and small plate dropped out. I have no idea where they were attached to the machine or the cabinet. Haven't been able to find any instruction manuals for this model or schematic details on the cabinet. I will need to find a new belt as well. Any help is appreciated.
