>>78566087There's no way to use the upper lenses, because the slide will hit the ground if lowered more. It's possible the intended usage is to use the lens slide horizontally but then this layout is dumb anyway.
The three lenses at the rear only make sense if this is a compound telescope with refraction off of the back, in which case the eye piece is the small protrusion at 30 degrees on the barrel. And if the eye piece is a single eye piece, being "quintocular" with 5 objective lenses at the front makes no goddamned sense at all.
