WW1 Period RFC / Early RAF Cigarette Box

A first quarter of the 20th century hand-made mahogany cigarette box bearing hand carved RFC or early RAF wings with crown above, originally there may have been a central device fitted but I am unable to confirm this as no old marks or impressions evident. The typical of the period velvet liner shows signs of age related wear in places but still retains a certain charm about it. The overall length measures 6 1/2 inches. Width 4 inches. Depth 4 inches.
