Military Provost Guard Service

[Alan O]

K&K list 2 types of the Norfolk Yeomanry cap badge and show the GV and GVI only as full sized until the EIIR version when a small beret badge was made.

The Military provost in WW2 had a small beret sized GVIR badge but K&K show the WW1 version with a wreath. The EIIR version gets bigger as it takes up a scroll.

Wilkinsons book mixes up the lot and gets very confused.

I always wondered if the small GVR badge was genuine. This belt is on ebay and looks genuine and includes the same GVR badge. Norfolk Yeo beret sized does not seem likely for WW1 so is it indeed Military Provost?

Any ideas?
Postscript Likely to also have been worn by the Royal Defence Corps whilst the wreath badge is likely to be Regimental Schoolmasters.
