Gillette single ring and that date code means it was produced in 1917.
Yep, that is a 1920's two piece old type like the one I have.
Look for a serial number on the top of the bottom razor plate. Not all will have a serial number but if you find one you can put the manufacture to a set year
Yes mine has the Number the same place as yours With the No E266131 here is a other photo of it in pieces cant find any other markings expect the word "Gillette" so would you say this was 1917 or 1930s
what are the ball ended ones called and they more 1950s thank you for the advice given allready
