A Few Assorted Mystery items For Identification Please.

[oc14]

As the title suggests, like almost everyone else I pick up items that I haven's really got any idea what they are. Here are a few for identification please.
1) A large (possibly Thai?) brass badge with three Elephants in the centre of the badge. Appears British made, 3 lugs to the rear
2) Possibly some kind of horse furniture ? Possibly Royal Fusiliers related ? The brass circlet with the motto is quite crudely cast, the central rose is much better quality. Two (fairly short)lugs to the rear
3) Chrome King's crown Bucks Constabulary WR (War Reserve ??) Badge. Any ideas on age (WW1 or WW2 ??) and whether it's a cap, collar or shoulder badge (or even something else ??)
Please be aware that all three will be for disposal once identified.

Thanks in advance
