These cufflinks are clearly marked with "Baer & Wilde" , also with "Kum-a-part".. im told they were made in the early 1920's. The circle decor is cream or off white in color with a navy blue color that has 2 parallel lines running across the face and around the outside edge. This circle sits in an octagon shaped setting that is not magnetic, so I believe the metal is silver or gold but I'm unable to test it. The posts of these prices are magnetic.
