Question about brooch

Hi all!
I'm looking to get a birthday gift for my friend. She loves antique English pieces, and I was thinking of buying a silver brooch. However, not all of them seem to have hallmarks, so I'm not sure how to identify whether they're genuinely English or not.
I've been looking at this fly brooch, but it doesn't appear to have any hallmarks. I also found this grouse-leg brooch, but the hallmark looks a bit unusual and doesn't strike me as English.
Any thoughts or advice?

 

The winged critter may be meant to be a cicada rather than a fly. The grouse foot has a very British registration mark, which some of our members are good at deciphering. The ones I've seen that were actual dried feet were Scottish. Someone will be along who can tell you more.

If the month letter is an E and the year letter is a D, then it's May 10, 1878
Or if it's a C instead of an E, then it's January 10

 

Agree re cicada. A popular symbol of transformation and rebirth in the Victorian era.

I'll just add that the grouse foot may be a kilt pin.

 

or hunters hat pin !

 

Possibly missing a stone

Good catch!

The cicada has a trombone clasp, marking it as continental European. The grouse foot is a Scottish design, and I agree missing its end cap.
