I am awaiting the return of the reproducer from my BC-34.
When I first examined it, the finish appeared to me to be a very dingy nickel plate: in attempting to polish it, I inadvertently rubbed it down to bare brass (mea culpa).
Since then, I have learned that the original finish was a bluish-grey gunmetal. I have been searching online for a solution which will replicate this patina; but the one site so far that offers a compound that will work on brass only sells the stuff in amounts of a gallon, at least.
Can anyone suggest an easy and economical way to replicate this finish? Would the bluing compounds used by gunsmiths produce an acceptable result?
