Remember, they did set a graphite pile nuclear reactor on fire over there, if anybody could blow up a Darne, it would be them. Dustin, I've got photos of the ancestor of the V action that has a crack in the sliding breech, but, the gun shows clear evidence of abuse, and likely dates to the 1870s. I'll try to get some digital copies one of these days. When ever someone makes comments about damaged Darnes, the first thing I ask to see is the name on the gun-almost always a copy.
Not all of them are created equal.
Best,
Ted
