Thanks again for the valve parts. By the way, my 1916 Holton appears to have solid copper in the valve construction. The top and botton caps as well as the cross rubes appear to be brass while the cylindrical portion of the piston is copper. There is no plating on the pistons. The finish is too consistant for it to be worn plating. The only explaination I can see would be if at some point someone chemically stripped the plating from the pistons.
I don't know a lot about horn construction but I can tell you that German silver is not much different than stainless steel. It contains nickel and is sometimes referred to as nickel-silver. It seems to me that this material would be very difficult to form as opposed to brass which is a dead soft metal.
