While I am more familiar with the Grulla sidelocks as I think more of the sidelock models are around. If you found one at WLM close to your gun and it says 2000, I think that is about right. They know their guns well as they have been in the trade a longtime. You can put any price you want in a listing and maybe sell it at a high price. But 2000 is probably a fair value for that gun.
