I have the exact same model gun. I got it because I had to make the spring that works the push lever to open it. Not an easy spring to make. I was telling someone and he had knowledge of someone who had the same gun that also needs a spring.
I contacted the owner and struck a deal to buy his gun since he was afraid of shooting the Damascus bbls. It was also missing a hammer and several screws all of which I made . That was 12 years ago and I've been shooting mine at vintage events and bird hunting ever since . I absolutely love it
