New tubes are welded in place.

Seams TIG welded.

Exterior surface struck up exactly as a new pair of barrels, with equal care and time spent, and then polished, then best blacked.

The seam is invisible. The barrels are profiled, balanced and weighted perfectly. The original rib is re-laid (unless longer barrels are required).

This is a job totally unlike what you will have seen done in the past. It is only worth doing if the action is of very best quality, otherwise the expense is not worth it.
