I used to have a Norma maintenance manual (and videos someone had put together) but mine seem to have been deleted and the online links to both are dead now

Does anyone have these they can share?

Also one specific question if anyone can help - how does one go about repositioning the swing lever on the 8x10 rear?
Mine is locked pointing nearly forward and I'd like to have it pointing out (perpendicular to the rail)
It seems like I'd have to get at some screws under the back tilt and would have to disassemble quite a bit to get to those?
