The 303 has been refinished entirely, well done though.
The 461 has probably had a barrel reblack but the action is untouched.
Must be the lighting playing with the engraving, the 303 has been laquered so is more shiny in the light. Both are crisp and clean and the 303 looks to be untouched other than the colors. Makes one wonder just how badly it needed the recolor anyway...
