If you need some buckles cut up the thin light brown belt its the easiest one to find
Thin Brown ones come with the soildier and british infantry late issues same as a thin green one obviuosly just match them as best you can to the rest of the uniform.
The underground rescue one is a real deep brown like chocolate colour i will get a pic of mine when i get home
Thick tan green and brown are that of the early issue soldiers,paras etc etc again just match them to the uniforms
Alot of mixing and matching went on mate i think palitoy just placed whatever looked best.
Sliders make them worth more but in genreal £2.50-£3.00 each
Hope this helps a bit ????
