I have an old German scope that is in perfect condition except it is missing the cap that goes over the windage adjustment. I have the other one from the elevation adjustment. Does anyone know where I might get a new one manufactured? I can use the one I have as a pattern for the new one. I assume someone can mill an new one or print a plastic copy on a 3D printer. Just don't know where to begin to look. The few inquires I have made with local machine shops have not been fruitful.
