In regard to polishing the barrels as shown by LeFusil and his comments above.

Desmond Mills, the former Purdey gunmaker supports and reinforces LeFusil's assessment stating in his book on Gunsmithing: ......"exterior of the barrels.....must be so highly polished that they look as if they are chrome plated. This forms the foundation of the quality and appearance of the barrel finish.''

Kind regards
