British Army trade badges

[Garth Thompson]

Thought I'd post a selectionof trade badges I've put together in the last year. Mostly Ww2 and some WW1 vintage maybe a couple of post-52. The point is to show our younger and less affluent collector members you can have the fun of decent little collection without spending large sums. Most of these can be found for very reasonable prices.
Hope you enjoy nthe pictures,

Crossed Swords Badge

When worn on the upper arm it denotes a Physical Training Instructor (PTI), but it also used to denote a skilled swordsman in cavalry units - one per troop if I remember correctly. It was then worn on the lower arm. The one on the right is Guards' pattern. The other is for the rest of the army.

Also worn by WO II's & CQMS of the Grenadiers as part of their rank badges. The current guards pattern was the pattern of "trade badge" worn prior to 1962, the army went over to smaller trade badges sewn in white, the guards kept the versions sewn in grey / fawn / brown.
