I used to buy some of my motorcycling gear from military surplus stores. My gauntlets were WW2 British Dispatch Rider's* and my summer boots were WW2 German troopers boots. My rain cape, for use on motorcycle and post bike, was an ex-RAF WW2 guard's rain cape. I also used to wear boots called 'ammunition boots' as a postie. They covered the ankles and protected them from dog bites. They were tough and normally hard wearing but as a postie I walked a lot so wore out a pair in about 7 or 9 months
There is one store left in Belfast. Still doing 'Army Surplus'. We have a very large number of marching bands and some of their uniforms are made up from Army Surplus uniforms
* I think I may still have them somewhere
