Gene, I got this far:

“Damon-Pétrik... This name is both among the best known in the French armory and the most poorly known. The superimposed products produced by this manufacturer, recognizable by their tile lock coming to style the cannons, are familiar to many of us, but we don't know anything

Of their history. It's time to lift the veil”.

Now, my brain hurts.

Best,
Ted
