I have what I believe to be a Singer industrial Class 16 machine, which I hope to use for making bags. I do not know the actual model number, the serial number is G5856178. It does have a two-part foot like a walking foot. I just had it serviced and tuned. However, it is still not working correctly. I was able to sew two 6” lines and it broke the top thread. Now I cannot get it to sew at all, it is not catching the bobbin thread. Any ideas?
I am also looking for a manual and a few parts. Any advice will be greatly appreciated.
