Backing plates?
 

What are the purpose of these, please? Two different types. Assume backing for something but would you know exactly what? Thanks for any help.

The double ovals are for badges with sliders.
Not sure on the others.

They are clips to fit on slide red badges to keep them tight against the cap. WW2 period. British

Apparently still available after about 80 years!

And at 24p a throw.......

I did see one in use fairly recently.
The last fair at Penkridge,there was complete bandsmans uniform to the Queens Own Yorkshire Yeomanry. I looked at the pouch badge to see the fittings as the badge was anodised cap badge sized. In fact it was a cap badge held in place by a retaining clip.

Pattern Number 11057 which is also in the correct sequence for 1940 items

So were these used in WW1 on slider badges and if so is there a difference between WW1 and WW2?

Rob

These date from WW2 (1940) only, but apparently seldom actually used during the war. Probably saw more use post war.
There were no backing plates for cap badges prior this 1940 date. There were, however, backing plates for shoulder titles and sleeve badges dating to before WW1, which are of course a different story.

Thanks for the info and clearing up that question.

Cheers Rob

I can't remember the detail re dates introduced but there was another pattern used, an oval plate with two circular holes in it.

The two kidney shaped plates with holes are sewn into the shoulders of uniforms to retain the strap underneath for shoulder cords.
The far end would have a threaded post plate for a button with a threaded shank.

Many thanks to everyone for sharing your knowledge. Particularly pleased to finally learn what the kidney shaped items are for. Puzzles solved. Thanks!:)

Original usage was for cap badges with sliders to be used with the Khaki Field Service Cap (Side Cap) to stop the badge rocking in use or falling out as there was no stitched pocket for slider.
