WW 1, Royal Naval Air Service Officer Tunic Should
A very rare WW1 RNAS Officer's tunic shoulder board.
This board has a small RNAS button at the top, followed down by a metal RNAS Eagle. This eagle is the same size as the one on the officer cap badge.
At the base is metal rank braid.
Board size, 4 x 2 1/8".
In an excellent condition.
