Recutting 140 year old checkering

This high grade Parker hammer gun was built in 1874 and was in good overall condition for its age.  However, the owner wanted the gun freshened up a little.  Along with a good cleaning, it got a checkering recut.  The original checkering was all visible, but was worn in some areas but mostly filled in with dirt and old stock finish that had been added.  The original pattern was all recut but not fully pointed as to maintain an older look.
