So whilst agreeing with Hamish that much so called MOD stock being sold is imitation: I do not find the sizes questionable in respect of outdated military clothing. Too MOD kilt can stay in the stores a very long time: in the mid sixties I indented for some replacement stores for the Vickers MMG-what turned up was perfect, yet still in its original 1917 packaging-nigh on fifty years. So I'd not be surprised if in some long lost store, there are not Boer War uniforms just waiting to be issued.
A story is told of a stevedore unit in France during the First World War, mostly African-Americans, who opened a crate of uniforms and found original Civil War Federal Army issue fatigue blouses (sack coats) and trousers, in their original packages! :mrgreen:

Cheers,

Todd
