That machine is a Consew made in Japan right after WW2 and is a direct copy of an old Singer 19...I'm the 3rd trimmer I know of to own the machine I traded two Morgan silver dollars for it about 5 years ago! It's been working basically daily since the mid 60's that I know of and it will still sew better than the new ones which are now made in China and contain plastic parts!
It will sew right through your finger bone and all without missing a beat...
