Yes I have done the same thing. I was taking a insurance survey of the firearms and marking them off as I picked them out, checked serial numbers, etc, and suddenly found a .50 caliber flintlock T/C Hawken on the shelf. I must have purchased it, and stuck it on a back gun shelf. It was even labelled so I knew what part of the rack it went in, and where I purchased it from. So I too got to shoot a new to me rifle. This was a while back and I have sense shot the devil out of the rifle. I purchased it so I could fit Green Mountain Barrels in a .50 Hawken instead of my .54.
