Thanks, Larry. If I read the post above correctly, the fine Seytre/Lacroix sidelock pictured is Belgian origin, finished up in France.

On the "barrels" by Verney=Carron, do you mean they make the rough tubes, too, or do they put purchased tubes together for more finished barrel sets ? I am not familiar with "Metro". To sort of clarify my thinking, I am really most familiar with pre WWII gunmakers and really don't "follow" guns made later. I understand that modern machinery can produce products in house that would have been hard to duplicate in house at the turn of the century.
