I well remember my grand father wearing spats,plus the kilt, whilst grouse shooting ,oh so many years ago and for a wee while my brother wore a pair of US Ranger(?)spats for the same purpose.The Rangers used to train with our Commandos in this part of the Highlands in WW2 and somehow a pair of spats were "liberated".Apart from band type spats I have not seen any for many a year.
