I've bought an Old Type from eBay and I'm not 100% on its provenance. Firstly arrived in the sort of bakelite case one usually finds later Techs in, and the head carries no Gillette branding merely 'MADE IN ENGLAND'. The build quality quality is a match to my other Gillettes of a similar vintage(see pic below), so is the paucity of markings a sign that had no patents to protect etc.?
