This is an original British Army bi-metal beret badge for the Royal Army Pay Corps.

The badge displays the post-1952  Queens  Crown.
The badge is identical to the cap badge but smaller.
This is the earlier 1950s bi-metal issue before the later anodised aluminium type introduction.

There is a little wear but most details are very  clear and present.
The slider is slightly bent 

Good British Army militaria.

Reasonably priced.
