Pre WW2 or fake wings?
I have some wings here that seem off somehow. I've looked in Silver Wings, Pinks & Greens and More Silver Wings, Pinks & Greens by Jon A. Maguire. Two great books and United States Army Air Service Wing Badges-Uniforms and Insignia 1913-1918 by Terry R. Morris. man, there's some collectors items there. On the overleaf of Silver Wings,Pinks & Greens there is a silmilar wing. But it is brass. Then on page 82 #17 of the same book is a wing that looks similar but it is also brass. These wings are not hallmarked but marked sterling. The catalog description says Sterling marked PB Pilot Wings 2.75", 8.4 grams. These sure look like aluminum, not silver.
Thanks in advance
