For Polishing Buttons army style.

I finally have managed to buy one of these. My Mom has one somewhere which belonged to my dad. They were issued to each soldier so they could polish their brass buttons without getting polish on their uniforms...The slit is for you to slide under your button..and I guess all the other shapes are for any other tricky bits of brass you light have on your jacket.
Bought from Vagrants boot sale near Crewe for £3.
