Recently got hold of an old Gillette ball end Tech from a local charity shop. But despite lots of searches on here I'm struggling to date it accurately. If anyone can tell, or suggest a useful link, I'd be really grateful. It has only "Made in England" and "Gillette" on the bottom plate, nothing at all on the top plate. Handle seems very heavy and solid. It came in a silver coloured metallic case, which was part of a leather toiletry set. Oh and it shaves like a dream. If I had to shave every day of the week, this is probably what I'd use.
