The work done by Westley Richards is top notch. The guns I have seen the joining is almost undetectable. I struggled with the question myself and missed a very nice, affordable Charles Lancaster because of my indecision. The gunsmiths doing the sleeves are probably the same ones who are building the bespoke guns. Another note it that a lot of the classic guns are 2 1/2" chambers, however, they all have to be proofed before leaving the shops. Just my humble opinion. DK
