Antique Singer Treadle sewing machine

Hello

I have what I believe to be an antique sewingmachine. I have never used a sewing machine so I dont know a thing about this LOL. I can see that the belt for the treadle is broken. Other than that I think its in great condition and it is a pretty machine. My mother in law used to sew on it years ago. She says if it has a new belt it would work just fine. The cabinet is good condition. No cracks no chips. All the cast iron on the treadle is complete and all in good condition. Any help or info would be greatly appreciated. Oh one more thing I do not have a key for the cabinet drawers but they are unlocked :) The machine serial number is #G9002613 and there is a tiny metal tag on cabinet with CAL MHS 114
