Good post. I bought a Henry Atkin spring opener years ago. The second time I was shooting it the same left lock cocking spring broke. Now that Atkin spring opener is the same principle as the Purdey. At that time I posted here on the forum as my local smith could not make that spring. That spring has a small roller at the top. That is why is is so unique.
A guy named Stephen Hutten responded to me via this forum and said he could make me one. He was a former actioner from Churchill I believe. It took him awhile but he got it done. He told me then he would never make another one.
Also, I went up to Gunter's shop a few years ago to take a gun. When I arrived he had a Purdey strown out on the bench. When I asked him about it I found out it was the same issue I had the time with the Atkin.
In a frustrated voice he said to me " See this spring, if it breaks throw the whole gun away".
When I went back to pick my gun up which just happened to be a Purdey as well I did not see the Purdey he had that day on the bench so I just presumed he had fixed it.
At the time my Atkin broke I believe there were only four people on the east coast that would fix it.
