Hi, I've recently acquired a Wollensak Velostigmat mounted on Betax n.3 shutter. The shutter seems fairly cooked, it seems to fire at the same speed regardless of what is dialled. I also would quite like to be able to use this lens with flash synch, so my questions are:
a) is there a more modern shutter I can look to obtain that this lens will fit on and that has flash synch?
b) if I get it serviced is there any other way to synch flash other than modifying the shutter itself?

thx
