Can someone identify this badge please.
It has a number on the back that looks like 742299. What is the significance of the number and why is there a 60 in the crown on the front of the badge.
It's the badge of the Returned Sailor's Soldier's Airmen's Imperial League (RSSAILA). The number on the back will be the service number, and the '60' on the crown on the front indicates that membership was paid for 1960.
A similar badge can be seen (except with a '95', showing that membership had been paid for 1995) on the Australian War Memorial site.
