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.
It is an open comb razor with an aluminium handle making it quite light, and this razor is in great condition, if you want a bit of local shaving history in your hands this is a good canditate!
The razor stands 78 mm high and weighs 32 grams.
