Rare Tryon built Mississippi Rifle

This is a M1841 Mississippi Rifle dated 1845, 1/600 built by Geo W Tryon. It appears to be about as original as possible. Not modified for a bayonet, field sight, but does have a steel ramrod. Still has 7 lands and could be original 54 cal. as if rebored it should be 58 cal. 
My uncle owned it for over 60 years, but has passed away and I have been asked to sell it. 
There is very few pre 1846 examples to be found, and this one is in very good condition, considering it’s over 180 years old and possibly used in 3 different wars.
