Larry,
Hmm. Reproof doesn't happen to actions brought in from Belgium and finished. Reproof happens after significant repair or modification that caused dimensional changes to the barrel and/or action after initial, existing proof.
Not sure what you have got there. Going back to at least the mid 1980s, Vouzelauds business model could be summed up as "We sell highly decorated boxlocks, and don't get our hands dirty doing it". The guns were built and proofed in St. Etienne, pretty much guild guns with a name on them. But, Vouzelaud is an old company, and likely had contacts outside of France. What else went on, as far as one-offs, or, true customs might be hard to discover from where we sit today.
Do enjoy it. I know I would. Might be hard to sell or trade, but, the pheasants won't notice.
Best,
Ted
