12th Lancers - 14/20th Hussars - Bucks Hussars

[Markus Bodeux]

Hello gentlemen,
i got this three cavalry badges in a lot of infantry and corps badges. They came from a collector in France and i guess they were "collected" after WW2. All the badges from the lot are in very good, most unused/unissued condition.
An experienced collector from the UK told me these three cavalry badges are good, from the period they were worn, and not fakes or restrikes, i hope you will agree.
I have no experience with cavalry badges and so some questions:
1) 12th Lancers, bimetal, ventholes, the lower parts of the lance pennants, the POW´s plumes and the coronet are seperately applied white metal parts.
I have found "tons" of copies and also some original badges, but they all have a slider to revers.
This one two lugs ... ? Is it a large collar badge? Height 53mm.

2) 14/20th Hussars, height 36mm with short D-lugs .... a collar badge ?

3) The Royal Buckinghamshire Yeomanry Hussars, height 43mm, short D-lugs ..... also a collar badge ?

Thanks for any comments,
kind regards
Markus
