Pukka,
Here are some more detailed photos.
Lock work

Stamps on conversion parts and converted parts





Remaining King's proof


Stamps on brass parts
"13" on thumb piece

"12" on butt tang

"D: OF B: C" on rear of buttplate. I have contacted the The Buccleuch Collection to see if it may have passed through their hands at some point.

None apparent on the toe, but, who knows. The other ones are indistinct, or almost invisible. This rifle has clearly been well used in its working life.

Other interesting things. I have noted on two, this being the second, British Ordnance guns, that there is evidence that hot irons were used in some portion of the making of nail holes. What is to be made of this?


The patch box compartment was enlarged, in the field, it appears.
