Been spending a lot of time on here!
Actually, I think the manual is a bit ambiguous on that point.
Under the flash section:
"The use of Nos. 5, 5B, M5 and M5B flash bulbs as well as electronic flash.
Nos. 6, 6B, 8 flash bulb is recommended for shutter speeds from 1/30 to 1/125 sec."
I think they mean that bulbs can be used to 1/125 but it's really not clear
(to me anyway). The later CS models do say 1/60 so I suspect that's what
they meant for the CS as well when electronic flash is used.
Just my guess.
