The name 'Minora' is very well known in South Africa, in fact for most folks a 'Minora razor' refers to any razor using double edged blades. These razors and blades were the most popular (and probably cheapest) shaving system in most areas of the land. Funny enough the actual Minora razors are very scarce, with way more other brands of vintage razors in circulation. My best guess on dating this razor would be late 50's to late 70's much the same as the aluminium Gillette tech.
This is quite a find, we have never come across one of these and it is quite a looker! We added a pack of vintage Minora blades should you want to add it to a display of sorts, but please give it a go with a modern blade first and let us know how it shaved.
The razor stands 80 mm high and weighs 25 grams.
