The 8x10 was a Durst, with I'm guessing, a Durst head (I'm not familiar with these) and filter drawers.
A 5x7 would be nice indeed, but I'd have to build a new room onto the house.
Vanbar Sydney is not very large, most of the consignment is in the loading dock.
Your last paragraph is correct--I didn't like to spread too much info, that's up to Vanbar.
As the State Library sells high priced silver prints off negs such as Dupain's "The Sunbather" I guess that they are outsourcing these now, or--heaven forbid--making digital prints.
