OK, Cliff LaBounty sold his business to Jim Dubell, who has a stellar reputation as a metal worker here in the US. He is at deltagunshop.com. Do not know if he is set up to actually start work yet. He got some training from LaBounty and is also apparently getting tips from Hamilton Bowen, who is famous for custom rebored revolvers. Have no idea whether Dubell plans to take on double rifles, which I would consider the equivalent of post-graduate work.

On reflection I think my 8x50R double, previously referreed to, was a Nowotny.
