Nice to see the fit went well, I put one in a TC and it was the exact opposite. Your touch hole isn't that far off, it wouldn't take much barrel movement to center it perfectly, I had to move the TC barrel back 1/4" to line up the touch hole.
Looks like it is time for lock polishing now to get rid of the orange peal finish.
Here is how the one I did came out after the polishing.

I used an old TC stock that I refinished, a NOS unfired .54 TC kit barrel and the L&R RPL lock, a friend saw the finished gun and had to have it, it has never been fired to
this day. I told my friend that these things had appreciated in value lately, I was really feeling him out to see if he might sell it back to me but he said he was really proud to own some of my work and planned to keep it forever.
