I recently cleaned out my "C" clamp drawer and got rid of many of them. These were also in the drawer and I figure they are old. However, they have no markings of any kind. Neither are they similar, the screw in each is a different diameter, thus they are not interchangeable. Anyone know who might have made them?
Inexpensive clamps for quilting frame.
The girls might be more interested then the boys.
I believe these types of clamps may have been also used to clamp the sewing machine to the table. Singer made similar clamps.
