If the Hallmark is actually for 1942, then your item is almost certainly genuine. A Hallmarked gold item of this nature suggests an officer's gift to his wife/sweetheart and must be very rare. I remember in the 1970s Charles Lusted offering for sale a Hallmarked silver Pegasus badge/brooch for sale - it didn't stay on his list for 5 minutes. I await with interest the view of the Forum pundits on this one. Am I right in thinking that the maker's mark is HS ? If so, it is an H. Samuel item, which adds to its likeleyhood of being genuine.
