I did some modifications to the Chambers Late Ketland for an English rifle. First, the "hook" at the top of the cock turns the wrong way for me. Just personal preference, but I like the look of the "hook" turning forward. Harder to do, but it looks more graceful to me. Here is how the cock came on the lock:
I TIG welded a blob of steel on the top of the cock. Here is how it looked before filing.....the look I was going for is shown at the right on another cock I made many years ago:
After a little grinding and filing, it came out like this:
I also like the look of a more "waterproof" pan, so I decided to modify that as well. Here is the pan the way the lock comes....
After some filing and polishing, it looks like this.....
I don't have all the parts done yet, but this photo shows the plate with the modified pan and the cock with the altered curl at the top......
