I picked this up on ebay a little earlier today and I've no idea what it actually is. I can't find anything on the Mr Razor site that matches so if anyone know, I'd be very greatful if they could let me know.
British Gillette OLD type head.
I have the same handle on a british NEW as well, so it could be a mix of parts.
The case I've seen similar with british NEWs and Techs.
So I think it's a british new set with a substituted old type head.
