Help identifying maker of these Cufflinks

[GuderianTA]

there are no other marks on these cufflinks besides a .925 and these two half circles on the clasp. Any help identifying the maker would be great.

The mark itself is about right for Kellwood Company which was founded in 1961 and is based in Chesterfield, Missouri. Apparently they were involved in the design and manufacturer of textiles, apparel and luxury goods, but I don't know exactly what items, so this is just a possible starting place for your mark.
