Hey, I see you live here in NC home of the Southern Side by Side event! Me and some of my friends shoot often , most Saturdays at different places here in central NC and shoot vintage side by sides. I have seen broken top lever springs on some of their Purdeys and broken ejector. I had a left cocking spring break on my Spring Opener Henry Atkin a couple of years ago and also a top lever spring. As you may be aware of that spring is almost if not identical to the Purdey.
It was expensive to make for sure.
I don't always shoot the same gun but try to rotate mine around.
Just make sure you maintain it and clean it properly and it should last a long time.
