I just picked up a pair of U.S. jump wings at a local flea market and I need some background information. They are basic jump wings, WWII type, with a solid back (not stamped) with pin and clasp. In relief in a circle on the back of the parachute are the words STERLING BY (G)RBER". I believe the first letter is a "G" but could be an "O".
I could not find any information about this maker on the web, or really any maker for that matter. My question is : Is this a WWII issued set of jumpwings or 50's vintage medal? Any information anyone can furnish would be greatly appreciated. Thank you
