I�ve possibly identified the �mystery� metal for the alloy that was used to make the center scabbard mount. Antimony, which is poisonous, apparently was popular at least 50 years ago as something that could be added to silver to make it tarnish resistant. At the moment I don�t know just when it began to be used which obviously could be earlier. Looking at the coloration, and some of the data, I suspect that the copper content could have been "bumped up a notch" also. FP
