Available for sale is a 1985 Engelhard 10 oz .999 Silver bar featuring a BorgWarner Chemicals 1,000,000 Safe hours award sticker for the Normar Plant. It is unusual to find one of these examples in such nice condition and to be sealed. Known serial numbers for this 'award bar' are 330469, 330476, 330532 with this bar being the highest of 330565.

If you have or know of other serial numbers please feel free to share and I will update this listing with additional accurate information. This bar is sealed in the original plastic, although sealed the bar exhibits purple patina as seen in the photos due to a none distracting 1cm crack in the plastic on the right front side of the bar.
