I just wanted to share my rifle with you all and maybe see if I can find out more about the history of the rifle. I bought the rifle from my BIL who had moved away from farming and rather wanted to buy a boat (a small boat). Anyway, he bought it from a farmer in 'maritzburg who had it for years as far as I know.
It's a Musgrave! 7x64, I believe it is a Mod 90, but open to correction. I already love this gun, can't see myself parting with it.

The number on the barrel is L90 0001. Not sure what the L stands for? But I believe the 90 is for Mod 90. Also, 0001 does that mean it is the first in this model and caliber produced?
Barrel is ~22in long, holds 5 rounds in the magazine, has a safety which is a bit tight but works ok.
I will try post some photos below.
