Hello - here is a higher res shot, unfortunately I'm not a photographer so its still a poor soft shot.

I am slowly formulating a plan. Recently I was able to bore-scope both rifles, the short one is not good at all. I am going to start with this short rifle, the basic steps will be to restore the bolt to original, have a saddle fitted to the front of the receiver to cover the dovetail, rings fitted and rebarrel to the exact barrel profile of the long rifle, which still lives in its original stock. Finally restock, using the long rifle stock as a pattern.
Sadly a supposedly "top gunsmith" I was recently referred to (allegedly trained in a top "London" establishment) tried to tell me that the "B, U and G" proofs on these rifles were british, which doesn't do much for ones sense of confidence in his knowledge !!
Thanks for the tip on SARCO for sights, I was wondering how to proceed with the cut-off ears.
Cheers - Foster
