Thanks, that could be it. I confess I've never handled a Drilling of a sufficiently early date to have pattern-welded barrels, but I can see how the hammer/Lefaucheux elements might fit nicely with that. I regret that I don't have an image of the action "table" (not so flat in the case of a Drilling!)
