Salvation Army instrument valves

Hi.  I am in the process of refurbishing the valves on some SA horns, baritones and basses.  At first, I thought that most valves were nickel plated on brass,  however, I am now convinced that they are made of Monel.  The color of the metal is not as bright as nickel, and have a slight hint of yellow.  The valves seem to be non-magnetic These instruments have serial numbers from 9000 to 12000 which indicates to me around WWI..  Monel was developed around 1906, so I am surprised that it was used for valves this early on.    Does anyone know for sure if the SA did make Monel valves back then?  Thanks.

It is also possible that SA made their valves of German silver, a brass with 10% nickle in it.
