This is the only other picture ...
Listed as a "1960s Vintage Razor" and priced VERY low, I just bought it. Seller was one of those Bygone Treasures kinda places. Unlikely to have got anywhere with them asking peculiar questions like can the read off the serial number from the inner barrel.
I'll know more when it arrives.
Exciting! We should run a sweepstake on which year it turns out to be ... 1905? 1906 1907 1908 1909. I'm hoping for the earliers, naturally. I think the 1905s had a sliding clasp on the case, although I'm a bit hazy about whether the British made go back that far.
