Thanks for the input so far. The lock is not flat faced. Gun is 46 inches long. Has original bayonet lug. I am not the best picture taker but here goes...
The stock is definitely not an Ordnance pattern one. The drop is much lower. This is undoubtedly a rifle commissioned for a volunteer rifle unit or for an officer's purchase. A number of British regiments authorized the officer's and some NCO's to carry Baker rifles. One of the major complaints from the troops about the standard 1803 Pattern Infantry Rifle was that the stock needed "more bend". Too high of a comb to get a good sight picture. This stock seems to have adjusted that somewhat.
Odd that they omitted the patch box. That was a feature missing from the 1776 Pattern Infantry Rifle that was desired.
The fact that the stock seems to have been roughed out with a patch box suggests that the guns may have been semi "bespoke" as was the custom of English gun makers for the civilian trade. Guns were fitted up with larger butts to allow them to be finally fitted to a customers specific dimensions.
I have noticed that the Morris Volunteer Rifles differ in stock particulars by comparing various photos. They have very different drops and comb lines. The example I own has a drop, pull, and comb line very similar to a standard Baker, but others have much lower drops, etc.
This might have been a rifle captured during the 1812 War by someone who returned from the fighting in Canada.
