Gert, your rifle is a real gem. I read Richard Harlands book "Ndlovu"...the best book about elephant hunting I ever saw. He really praise those M-S rifles..!
I have but two old M-S rifles, a mod. 1910 in 9,5x57mm, standard take down made before 1924 and a lovely 6,5x54mm made by charles Lanchaster in 1906.
Workmanship on these rifles is indeed very high..
