New and looking through old family badges

[SH_Berkhamsted]

I found:
- Duke of Wellington's Regiment in two versions - one for each battalion. Certainly my great uncle was in the 2nd Battalion on Western Front, Macedonia and post WW1, Ireland where he was killed.
- KSLI - not so sure to which relative these belonged to but one side of the family came from Shropshire, so it is perfectly logical to have these.
- Some Home Guard shoulder flashes (my father) and some unused sergent's stripes (a level to which I don't think he reached)
- various Somerset Light Infantry - logical as I was brought up in Taunton

But I don't recognise this:-
