Welcome to the Strelets Forum. Please feel free to discuss any aspect of 1/72 scale plastic figures, not simply Strelets. If you have any questions about our products then we will answer them here.
Here is a low res scan just done on a flat bed scanner hence the unusual angle.
I like a challenge. The plastic rock is the one I use and it normally travels 1cm vertically but occasionally forward with the force of comatose gnat. The hook is made of wire and attaches to the winding gear with a loop that pulls away. In the pic it is in the display mode ie under tension.
