Brass Demi Parure of Mesh Ribbon Pin and Screwback Earrings Very Rare Pieces

This is a very unusual and rare demi parure of clip on earrings and a lovely brooch. According to the patent number on the back 2066861, it was patented sometime in 1937 but it could have been made anytime after that.. The brooch is huge measuring 4x1 3/4" and the earrings are 1 3/4x5/8". All pieces are in very good condition but they do show signs of wear. The only mark is the patent number that I can see.
