I have a original 3rd Model Brown Bess that I need to place a value on. Its completely original and has been in just two collections for 50 years. No damage anywhere, functions perfectly needs no work on it at all. All proofs on the barrel are perfect and the GR & crown plus TOWER on the lock are perfect as well. I remember dating this musket to about 1808 by a couple of features years ago. I bought it from a serious collector 30 years ago who was reducing his collection due to his age (75 yrs old) at the time.
Any help or comments is appreciated.

Regards,
Don
