Not to disagree with Jimmy but at the beginning of the Thiers Issard Co the scales shape didnt have the pointed ends as you can see from this link:

Your razor with the trademark " Le National" registered in 1913 ( see the registration on this link:

Originally didnt have pointed scales. That said it is possible that the scales are original.It does look to me that the pins have been removed or played with at some time. Nevertheless im sure it will be a very good shaver, Enjoy!
