Make a note about what PeteM and Daryl H. say. The first rule of restoration is "Remember what it is". Crescents are all sharp edges and crude machining. Preserve that next time.
Your efforts should be tuned to that concept.
Make every effort to "preserve the light", and keep your efforts to the same tone. If you don't, you end up with an assembly of parts, rather than a nicely refreshed item.
The barrels are finished to a different condition than the rest of the gun, and it is a mismatch to "what it is". It's OK to allow old things to look old.
Just my two cents. I know you worked hard on it. As your eye develops, you will help things return to what they "are".
