I wouldn't be in a rush to have a company build me a gun outside their area of expertise. The employees that built sliding breech guns for VC are long gone by now. The "bits" that go in a Darne are a lot different than those in a sidelock or a boxlock. Look at what Purdeys went through to get their new hammerguns right.
Every Darne has to be weighed on it's own merits. This is of course true with any gun, but, with fit, especially, changes are tough. My copy, traded to me by Mr. Steve Bodio and restocked to fit me, while I stood there and tried it as he went, by Bruchet, is likely to be the only Darne I ever see that truly fits me.
A Darne that doesn't fit is no prize.
Best,
Ted
