This Gillette Tech razor was made for about 30 years in various countries using various materials, as far as we can tell there are no set rules on how, who, and where, what materials were used with certain models, so I'll simply judge by weight and visual observation and give as accurate a description as I can.
This Tech (no date code) is Brittish made and has nickel plating that is in very good condition. The logo on the top cap is still clearly visible with very little fading. it has no plate loss and if well cared for it will look te same way for another 60 plus years.
The razors weighs 63 grams and stand 82 mm high.
