Bottom line: sleeving and rebarreling done right are fine for using guns sold at the right price. The great shots of the 1900s, the original customers of bespoke gunmakers, rebarreled their guns. If it was OK for them, it is probably OK for us.

The collecting thing is a little strange for bespoke items. It is like collecting Savile Row suits, OK for tailors who want to study the stitching etc, but kind of strange for users of the item.
