My new-to-me DH has a ventilated rib, and when you hang the barrels on your finger by the lug and tap them with a wooden screwdriver handle, it 'thunks'. You can hear an underlying ring, but the muzzle rib post is visibly loose at the solder joint.
Also, the forend lug looks to be sloppily re-soldered at one end, but that seems tight.
Who can re-set the rib, and does it involve a total refinish?
What's a ballpark cost? Thanks again for a great site!
