Hi guys and gals

I saw on a YouTube video a 10x12 back fitted onto a Dorff V8. This appeals as a wetplate photographer I have plate holders and backs (mostly international backs from other cameras) 5x4, half plate/5x7, whole plate and of course 10x8. Does anyone have one of these backs that could send me measurements which I could give to my woodwork guy? You can see one at 1min into this video http://www.youtube.com/watch?v=hTXuO9MRfR4&sns=em

Thanks

John
