This is a musuem quality reproduction of what is believed to be a WWI Zepplin Crew Badge or Staff cap badge of the Zeppelin Company. Who knows for certain. Another name I found for this is WW1 Zepelinwerke Badge. So everyone take your pick. The one that comes up most is crew badge. In any case this reproduction is about 1 3/4 inches tall and has brass flat wire tabs in the back. Made in Sterling Silver and hallmarked 925.
