Silver wash is pretty flimsy. So I'd say it's a good bet this had it, if you look close you can see it in the ridges if yuh have one like this. I have one that looks like this with just a dot of silver on it. But to answer your question, yes I do believe there were other materials or at least colors. Odal will be able to shed a greater light on the subject than me, however. So he may have another example or two to show.
