The attached badge is an old USAAF or USAF officers cap badge, 2 1/2" h. with screw fitting & nut at back.
The reason why I am unsure is that it came to me many long years ago in a framed collection of mainly WW1 & 2 cap badges. , so I have been conditioned to ascribe it to WW2 period.
Then again, it has a backmark in the hollow of the shield: 'LUXENBERG - NEW YORK - MADE IN ENGLAND'. This further strengthened my belief in a wartime provenance.
However while browsing US insignia forums, a similar badge was ascribed to the Korean War (1950s). Flying Tigers Antiques describe is as rare.All web sites featuring Luxenberg badges have nothing but praise for badges by this maker, citing them as highly collectable and gems.
So, having said all that I really would welcome being able to have said badge positively identified and placed in its proper time frame.
