Manleigh Chatelain tie bar from 20’s or 30’s. With marqasites.

A great looking chatelain tie bar from about the 20's to 30's with a drop with the initials DB in marcasites. There are three (3) marcasite stones missing. They are not real noticable, in fact I did not pick up on this until I took a loupe to it. The bar measures approx. 2 1/2"X5/8". The drop is approx. 1 5/8"X1" and the drop is approx. 2 5/8". Back of the drop is marked sterling. Back of bar is marked Manleigh.
