History / Interested in Polish Camping history [3]

Hi, my grand parents ( father side) were Polish ( I do not speak it, but understand a little), they settled in South America just before WW2, and I always heard about the life in the old Poland, about the snow, the places and trips they did, one thing that got me interested was about camping equipment, I wonder if anybody knows where I can find information about pre war tents, lanterns, traditional gear, etc?...my wife thinks I am a little "cuckoo" about camping, but in a good way, I would love to know more about Poland.
