SGJ, what is it about the Lang single bbl that prompts your feeling of fine handling quality? Light/heavy weight? Balance point from trigger? Short/long bbl? Light/heavy stock? How does its handling compare to a typical Brit game gun? Typical Brit game gun has the following handling characteristics: 6 1/2# weight, 4 1/2" balance to (front) trigger, unmounted swing of 1.45, and mounted swing of 6.4 (average of 60 some guns).
It is both possible and practical to sum the parts/assemblies of a gun to see where the swing characteristics are coming from. For example, measuring the weight, balance, and MOI at balance for a set of barrels and forearm (assembly) and for a stocked action would give a "which was causing what" for that gun. I have now two positive experiences of specing the restorative work on quality "orphaneds." Per Dig Haddoke's theory of restoring best work guns to usefulness and owning a best work gun for about 20% of new, I have tried one with high quality barrel sleeving and another with a restock. In both cases I got what I wanted for what I could afford. I'm convinced that it is possible to spec a gun for handling provided you actually know what you want. That is to say replicate the handling of one gun to another.
