11 Mostly British Cap Badges to ID

[TomboPC]

Hi All,

I've just started looking at my collection again after many years and have drawn a few mental blanks on some of them. Can anyone jog my memory?

A. Grenade 7
B. 2 x Star bearing quartered shield in different metals
C. Elephant
D. Non-British artillery
E. Non-British Horn, crossed swords and 1
F. Prince of Wales's feathers
G. A massive (2.5"x2.5") Victorian RA badge. But what is it precisely?
H. A smaller Victorian royal crest similar to [G]. I also have with K/C.
I. W/m shield with 3 balls and 3 cannon with brass crown and scroll
J. Brass star under K/C bearing shield with books? and rose
K. Royal Cypher GvR but without crown

Many thanks!

Tom
