Fascinating gun! just when you think you must have seen it all something like this turns up.
I was wondering what seem different with the Martini part then realised - no cocking indicator.
As to the case lock being ineffective against thieves, I remember seeing in a sporting book from the Raj a recommendation that cases should be lockable to prevent railway thieves substituting an equivalent weight of stones for the contents to avoid early detection.
Hello Parabola,
Thanks for the reply.
I never thought of the "rocks" substitution. The lock will protect against that.
