Me and my shooting buddies shoot reguraly with vintage English guns. One has a 1909 Purdey and another has a 1880 Purdey hammer gun. I have another friend who shows up with something new about every week.
I and my bud's have had our break downs. My Atkin broke a cocking spring. It is an "Spring Opener" much like a Purdey.
Now that was an expensive repair.
Shooting low pressure loads work great and you should enjoy your gun while you can.
