Mle 1907/15 Mannlicher/Enbloc clip question.

[Bundook303]

I have a Remington Mle 1907/15 that looks like it may never have been fired. I understand that the French refused to accept the rifles from Remington citing quality issues, and that Remington sold the rifles domestically. Does anyone have a clear idea of what the manufacturing problems were (bore dimensions? chamber dimensions?) and whether they would preclude me from eventually firing this rifle? It would be interesting to hear from anyone who has already ventured down this path. Many thanks!
