I have an older (but still in the box!) Toyo D45A purchased in the early 70s whi ch I'm going to start using again....Just curious what the current equivalent mo del/cost is. Its not a field camera. It is a single rail all metal (I think) w ith full back/front swings/tilts/slides. Ground-glass back/filmholder can be un clipped and positioned vertically or horiz. Any ideas?
