Congratulations, she looks like a winner. Please take photo of the top lever works and foresight and proof marks for us double rifle lovers. The rifle you have and many others like it were the fail safe work horses of the bush in Africa and India.

Even though the barrels have been re-blacked the engraving is till sharp, are the barrel bores in similar good condition.

The Westley's and Jefferies DR made for Lyon are sought after.

Consider if you should shoot solid projectiles through the barrels, until you are certain that the barrels can tolerate the "stretch"

Kindest Regards;
Stephen
