Probably no name on the rib.

I usually have the barrel maker engraved under the tube where the forend covers it, in small lettering:

"New Barrels in 2012 by B. Blacker & Son (Formerly of Holland & Holland and James Purdey & Sons).

For example.

Where requested it may be possible to add the Woodward name to the rib for appearances sake but the identification of the barrel maker as independent serves to avoid any chance of a buyer being deceived.

The prejudice against sleeved barrels is understandable when looking at some old work but I very much doubt Mr Martin or Buzz would be able to tell a best sleeved job was sleeved without looking at the proof marks. The job is totally unlike it used to be when done to the highest standards (with corresponding costs). It is still cheaper than new barrels.

The bottom line it that the gun will be affordable to some and equal in looks and performance with best sleeving. With new barrels it would be out of reach of many of those people. With some of these older sidelocks, sometimes it is the best way to go.

New barrels retail right now are 8,500.
