Stephen,
When I was 14 in 1974 my dad traded for a K-22 just like the one in your photo with no finish left. I saved the money and sent it back to S&W and they completely refinished and retimed it. I believe it cost me $57.50 to have the work done and took about 6 months. It shot great but like a foolish kid, I saw something else I thought I had to have and traded it off. Have been sorry ever since.

I think I'll start looking for a replacement after seeing your photo.
