Mark,
Do you have a pic of the ribbed butt after refinish? Did you recut it or leave as is? I am still kicking myself for not pulling the buy it now trigger on this gun- I had several questions for the seller and was probably reading the e-mail with answers when you bought it.
Wow, I'm glad I pulled the trigger when I did then. I know what that's like though. I knew someone would snatch it soon if I didn't. I did re-cut the butt a bit, but not extensively. It does look better now:
As a special order gun with a 24xxx serial #, Uncle Dan apparently saw no need to stamp the grade on the frame either:
