Identified in auction as French Musket 1814

[SiHawks]

Hi - can anyone please help me identify this firearm .The auction called it a French Musket 1814 - I have little to no experience in this area but I am doubting this now having done some brief online searches. 
 

Thank you.

Can't really tell much from the picture but an 1814 musket would have been a flint lock so at best this is a later conversion to precision and no longer a true Model 1814.

Thank you qed4 … does this photo help ?

I honestly don't know what this musket is but I note the piece appears to be percussion, not flintlock which would be appropriate for 1814; although it could have been converted to percussion well after 1814.

Could it be an 1841 Mississippi - measurements seem to be similar?
