Thanks for your compliments. The day was magic, with that storm about to break, and experienced reenactors came from many places of Spain and Portugal. There is a proposition to repeat it in Belmonte (Cuenca, Spain) every first weekend of September.
I was just taking photos. But I made some performances with my group of fencing, too. An armor like those (fully functional, not just for fancy dressing) may cost about one thousand euros or so, maybe more. It depends of the model, size, etc. You may buy it also in second hand market. A good sword is over 150 euros. If you want it only for dressing, you may find them for 50 or less. The kind of things made for tourists.
