Somehow a post I made last night disappeared early this morning - so here it is again.
Looking at the major support brasses on my tailboard cameras, the thickness of the brass is as follows:
18x24cm camera - 2.5mm
30x40cm camera - 3.25mm - but with additional thickness near the base rail (place for a slot which fits onto the rail) 4.5mm.
These are all flat brass pieces.
