Just because someone lists a gun like that for, let's say, $800.00 on GB doesn't mean he's going to get it. There are a lot of 1816s out there, most of them with the Belgian percussion conversion which makes them the least desirable variant. They are generally considered not safe to shoot, if one is looking for a musket in shootable condition. Lots of N-SSA shooters shoot original 1816s with patent breech conversions. Obviously the stock is useless and less than attractive, even for a wall hanger. The ramrod is an incorrect replacement. So is the nipple with a cone that's too high, hence the nonalignment with the hammer. Given the poor exterior of the barrel, one could assume that the bore is not much better. As the gentleman noted, we all have opinions as to value. To me, it's only value is in its usable parts. I wouldn't hang it over my fireplace.
