I will say the resolution on the photo doesn't help but I can't make that lock signature read belknap if I tried. Looks like belkuhe or belkune.
Oh, it's a fine John Belknap target rifle alright... rare as hens teeth and hard to track down.
To my knowledge there are only three of these beauties in existence that survived, there may be more however... The most visible one these days is likely the first, second, or third he made. It can be seen at the Shelburne Museum in Vermont...
Number five or six if my theory is correct, is the rifle that started this thread... The one that Blacksmoke found in the Auction ad is likely number four... and there should be one more built on this theme from the same log of wood.
In his article, Dave Wood suggests that Belknap would acquire exquisite logs of exotic wood and mill them to get 3 excellent blanks and build the rifles as the wood moved him in 3 variations on the theme. It is pretty obvious that no two were made the same. I could be all wet in my assessment... but it is fun to investigate and speculate...
Belknap drowned in a boat accident during a flood on Nov. 27, 1888. While trying to save a log of fine hardwood from going over a dam, he tied onto it, but too late as it pulled him and his boat over the dam as well... He was a blade smith, hydrologist, and mechanical engineer, tool maker. and had been building fireArms in his spare time for most of his adult life, especially in his last years... he was 48 when he died.
Had his life not been cut short, he doubtless would be very well known if these three examples of his work are any indication.
