Hi
apart from the fact that I am jealous as hell that you have this beautiful piece and not me - looking at your pics I saw a photo of a Colt Woodsman Match Target which brought back memories!
The Woodsman Match Target was the first target pistol I owned back in the old days in Germany, about 1966 or so - wish I still had it.
Re cleaning the engraving: I assume you are referring to the action (metal - nitrite finish if I remember the term correctly)
I only use med. alcohol and Q-Tips on that with good results.
a soft brush (like a toothbrush) helps
regards
