This is possible, too. If only I had a drawing about the inside of my scope... The only sure thing is that in 2010 S&B engineers had found something and tried to fix the problem, with some partial success since their new scope don't move between 12 and 24 degrees (so it's a perfect 'summer scope' here in England but would jump twice a day on the continent).
