I found this and have never seen this Gillette Tech set before. It is similar to "The President Statesman" that Pan America gave away in the 50's. The Tech razor has a date code of K 3 so 1965. The cap has a roman soldier head. No other marking on the container.
Here is my Pan American set. The razor is an A 4 so 1955.
