As well as having film holders for the V700, they also sell ANR glass to suit. (I keep meaning to buy some stuff from there myself...)
(Sorry, just realised that you said "in Oz", they're not. My mistake.)
Thanks for the like. I do have a Betterscan 6x17 holder, but this is for a 7x17 holder. Inches, that is. Doug didn't want to make me one, so I've had one fabricated. Now need to see if I can get some glass.
