In terms of commercial success, The Henry Rifle Project was a complete and utter failure. From a profit and loss standpoint, the historical scales will forever tilt heavily toward loss. Still, more than anything else, Henry Rifle was a lifeboat launched by a man who was sinking rapidly. An emergency buoy fired up from the depths.
Even if that lifeboat never reached new worlds and did little more than drift about in vast and empty seas, the fact of it is, it kept its lone occupant afloat-alive.
From that viewpoint and that viewpoint alone, The Henry Rifle Project was an unqualified success.
