What it says on the tin - any spare colpack heads, no number too small. Have other plastic bits for swappsies if required, otherwise will re-imburse postage and buy you a pint at Partizan/Colours/Warfare.
Please note - NOT the colpack heads in the French Hussar box, as they "dress to the right" as regards the hanging bag, whereas I need chaps who dress the other way, as this is for a Peninsula/Nassau-related project.
