New Junker Ruh SD 28 bobbins „Unterfadenspule“ made in my workshop in Berlin. The bobbins have the same measurements and characteristics like the original bobbins.
The bobbins also fit for the Pedersen Model 308 leather sewing machine.
I have also needles for the Junker & Ruh SD 28 available. Please follow this link:
