Original WW2 period RAF flight sergeant brass rank crowns with original pins and backing plates.
These crowns were worn on both the four pocket OA tunic and the Battledress blouse by aircrew and ground crew above the Sgt stripes on each arm.
Slightly mismatched our as the lugs are vertical on one and horizontal on the other but still display nicely together. These badges are often found as slightly mis-matched pairs and were almost certainly issued this way.
A nice original set ideal for a badge collector or someone who wants to badge up a uniform with original badges.
