RFC Officer's side cap.
A good used example of a WW1 RFC officer's side cap. Quilted lining with large silk tailor's label for a London outfitters with RFC buttons and a bronzed O/R's style die stamped cap badge. All insignia appears to be original to the cap with good patina and impressions left in the whipcord material. Minor mothing in five places with a slightly grubby, used interior. A good, honest example
