Thankyou Argo, success with the pictures.
Unfortunately no case with the gun, so no label.
Definately only 2008 as the serial number.
30" twist barrels which have been refinished at some time. The top rib signing is faint but does states address as previous post.
The London and Birmingham proof houses were only stamping the bore size, in addition to the proof marks, from 1855, hence my supposition that the gun would be post 1855. Marks and dates Chart below.
The gun has an interesting trigger guard, which i have never seen on an English gun.



















Hopefully the question of date can be resolved! I'm sure i once read somewhere that Joseph Charles perhaps kept back some numbers for later use, which might explain? My only other thought is the gun may have been rebarreled in the 1850's, keeping the original early number but displaying the address at the time of the rebarreling? But hard to imagine the original barrels could be worn out in such a short time, unless of course a major barrel burst?
Cheers
