Yes, it was one of the 350's - it is a 1904 / 1905 rifle so that will probably date it.
I can't access the rifle to look as it is in Storage and I can't even get to the case / notes of mine ATM.
Thanks for the compliments - the person who owned it wanted someone who would appreciate it so I will look after it before I pass it onto someone else.
I want to add another one to it so I have 2 of them so hopefully that plan will come off. I've never owned a 350 of any sort so need to tick that box !
