I am restoring .
I am restoring a demascus grand with the round bobbin rotary treaddle like yours. 6 drawer cabinet. It was totally frozen .in my excitement to get started I failed to take a picture of all the workings and have no books. Have been unable to find any specifics on the working of this machine's parts. Could you possible take pictures of it's working bobbin area and under machine? And post them on here?. I would be so appreciative.
