The one with the H.F center is shown on the RBL website.
Unless the rules have changed you are 5 years out with awards :
After 15 years : Brooch for ladies and Tie Tack for gentlemen.
After 30 years : Long Service Brooch (for ladies)/Medal (for gentlemen).
I've got the 30 year Brooch with bars for 35/40/45/50 and Medal but not the 'pinned style' bars.
The one I'd love to acquire is the 50 year badge !
