Re: Military Ring Question
I would suspect that the ring dates to world war one. The reason for this is the inscreption 217 Aero Squadron.
The United States dropped the Aero Squadaron befor world war two. They aviation units became fighter/persuit squadrons, bomber squadrons, patrol squadrons etc.
I tried a quick google search on 217 Aero Squadron and found nothing. How ever on Yahoo I found an entry about a
Lt Harry Cambell Preston being transfered from to the 217 Aero Squadron flying out of Tangmere. When I opened the link it was a brief synopsis of a book that had the war time experienes of many different people in it.
Tangmere appears to be a joint RAF/Army Air Corps training base on the coast of England. It was used for the training of aircraft crewmen (mainly bomber crewmen) in world war one. I suspect that the 217th Aero Squadron was a training squadron posted at Tangmere.
I hope this helps.
