M49, M50 and the like cases are nearly identical to M18 but luckily do not have the crappy Slava movement.
Mine stops running all the time and winding it gets so heavy that you think the winding stem will snap for the second time.
Lessons learned I reverted to winding it on a winder only, but now it even stops running in the winder. It will need another trip back to HQ I guess.
I hope cman has more luck with his Slava though.
