Raimey,
The small lever attached to the forend seems integral with the engraved inlaid tip. There doesn't seem be evidence of rust in the area, but it could be bound. Are you saying that the little protrusion, or tip, may need to be moved to the left? That's interesting...lateral movement I have yet to try. The big horn lever moves to the right opening the gun for loading. I'll try pressing the forend to the tubes and move it to the left tonight. My Schindler is similar to the one on gunbroker, except for a more subdued (rounded) cheekpiece and more elaborate horn/metal trigger guard design. Thanks and all the best, Jorge
