Any ideas on when these blades were manufactured and packaged in this particular blade dispenser? It's definitely one of the more unusual dispensers I've run across.
Here is a news story about their debut in 1949

It appears ASR stopped using the term duridium in 1953. The Silver Star blades continued to be produced at least until 1960 (the last reference in google news archive is for the blades being in a sale ad during that year).....
