I was already very close to matching with my M1903 and the Warner & Swasey M1908 scope, but could finally top it with a later M1903 and the Warner & Swasey M1913 telescope. To be able to top that with an all matching M1903 with M1908 telescope will be a tough task to do!
PS: the hole drilled in the dovetail of the M1913 scope is to affix is to the scope rail on the rifle. They often became loose in the field, and this was the solution to properly fix it to the scope rail and can often be found.
