OK, another link, this one to an unfinished project. http://members.optusnet.com.au/~paul..._panoramic.htm
I'm only shooting colour transparencies with these cameras with the intention of scanning and printing via inkjet (still to be bought). I've got a Beseler 45 enlarger and I suspect that it might be possible to file out a carrier to fit 6x14. The diagonal of a 6x14 neg (56x140 actual) is about the same as a 4x5 neg so there should be enough coverage.
