Good news! I have been in contact with a gentleman in Miamisburg Oh, who is a volunteer for their historical society. He has sent me some very interesting info on Nelson Clark. I thought I would share it with everyone, since the rubbing off of the gun that is on loan to their museum is in my opinion identical to one in my possession. I am without a doubt not a professional but, I am 99 percent sure this rifle was made by him. The gentleman from Ohio also sent me a bio on Nelson Clark from The History of Montgomery Co. written and published in 1882 by the Beers & Company. I wont get into much detail, but he started his trade in 1825 in Miamisburg Oh. and married in 1828 and had two daughters. He also lived here until his death in 1859. He was 58 years old. He was a natural botanist, practical chemist, an inventor, a musician, and a fair German scholar. He learned his trade in Lebanon, Warren County OH. at around the age of twenty-one. The entire weapon he made out of rough iron and steel, The N. Clark rifle an arm familiarly known throughout the west. There's also a picture of his house sent with the package that still stands today. There is an addition on the left side of his house that is believed to be his gunshop. I really need to get this gun cleaned up and it just may make it back to Miamisburg. I think that would have made dad very happy. Unless I feel a hard slap tonight in the middle of the night.
