1919 singer sewing machine ?

HERE IS MY 1919 SINGER SEWING MACHINE It has been made electric but can be turned back to being used as a hand operated one .I have all the necessary things to do so . It comes in it original boxing with the key to unlock / lock the wooden carry case . Also it has lots of extra bits with it . It all works very well :-). The code that is on the sewing machine can be checked to confirm age and other info just by searching the singer sewing machine data base on the internet free . Any other questions please ask . Thanks Rachel
