There are several good ways to repair a rotary top lever that are both undetectable and will not break the blank. The rotary bolt is internal and not that costly to replace, additionally the rib extension can be built up with TIG and refit. I am not interested in taking on the repair. The lever being to the left certainly indicates plenty of use as does the lever being hard to open. The description of the gun sounds like one I would pass on but the the lever issue is not the end of the world.
