I have a model dragline that I no longer have a use for and I will GIVE it to someone who is willing to come to my house and pick it up. It is NOT a scale model, just something I made to play with my grand son. It works good and would be great for some ones kids to play with and learn on. I have no way of posting pictures any more but here is a video of it working if I can get it to post.
