Wonderful camera , extremelly beatiful and classy. I wish you a great success and great oppurtinity for Polish photographers.
May be you could build wooden tripod for that jewel. Is there big format film sellers at Poland. I think not camera but film prices would be tight the wallet. May be you can import Russian film and sell online if they are cheaper.
May be a back from Scanner array and digital option would interest the digital people.
I contacted with many companies at Europe and they sell Sony Linear Scanner array and fitted card and connected RAM for less than 25 dollars.
I think the greatest thing is to build 6x6 , 4x5 and 8x10 scanners for camera backs.
Best wishes to Poland ,
