Hello! A few questions:
Can you use traditional leather straps on curved lug bars or do you need a strap that has a curve?
If a special strap is required are they hard to find?
Is it hard to find 19 mm spring bars? 20mm?
If curved bars are 20mm, is that 20mm before having a bend or after?
One long shot question - I just got a Raymond Weil Maestro and I think it has curved bars, any idea if straight bars will work or is the curve needed to clear the case? Photos below.
