If you would need help with something, please feel free to contact me ! Here in Czech Republic we are reenacting Hungarian royal army, and we have plenty of materials, stuff, equip and photos =)
True is, that most of things can be only found in Hungary, Slovakia, or here in Czech Republic.
Uniform, bread bag, and cloth pre-war gas mask case are made only in Hungary.
Belt, ammo pouches, bayonet sling etc can be bought also in czech republic, because its similar or same as Austro-Hungarian equip in ww1 and also as Czechoslovakia army equip during 1919-1938.
Here is a shop with repro equip, and I have to say it is really good looking and also of big quality.http://www.kukreplika.cz/en/
I will try to find the shop with uniforms also.
But its not that easy, if you are not from central Europe.One of our members is working in Hungary now, where he has contact on the guy, who is making replicas of uniform and other stuff.So, its not that hard to get it into Czech, Slovakia or Austria, but its much more harder to get it into USA.
From the original equip you can usually found only helmet, water bottle, tin gas mask case, and if you are lucky also the mess tin, but they are quite rare to find.
Excuse my bad english
