Many thanks Griff.
Here is a link to my Lonsdales:

Both tang or tongue and loop are quite different in shape and style in my opinion.
Whilst not overly common I’ve seen various officers badges (marked) by both Firmin and Gaunt with the same fixing arrangements, so certainly it wasn’t unique to Garrards.
As Dean said a nice badge.
