I found the clasp below for sale on a Russian auction site. It is advertised as a copy. According to the seller, the picture of the cross with the clasp (lower) is supposedly from a book. The seller cites an August 19, 1917 decree approving this clasp for wear by officers on their St George crosses to differentiate them from ordinary soldiers.
Can anybody confirm such a clasp really existed? This is a first for me…
