Air Force Squadron Patch 510 Tactical Fighter Wing Babylon 5 Golden Gate Bridge?

Description

This is one several  Patches I am listing today (see my other auctions, including my ebay store) that come from a Patch collection. This
Unknown Squadron Patch is approx 3 x 4 inches.
I have scanned a quarter (similar in size to a one euro coin) to provide an idea of the size of the patch.
