In a 1995 View Camera magazine, an individual (no longer contactable) advertised a Toyo 810M and added '11x14 back included'. While it's possible this was a typo, has anyone heard of such a thing? How difficult would it be to achieve, and would the bellows be large enough to cope with the larger image circle required, or would it also have to be changed? I realise you can do just about anything to a camera if you put your mind to it, but I'm trying to work out if it would be possible to make a back change to 11x14 and possibly back to 8x10 that evening, with minimal equipment (or to have a reducing back to 8x10 if that's more practical).
Anyone tried something like this, even if with a totally different body?
