2holer thanks for the information. That muzzle picture is actually of the muzzle of Stallone's Remington hammergun that I stole from his post earlier in this thread.

Yes, the keels are those triangular pieces of steel used as filler. They are very nearly universal in factory muzzles of Ithacas, Foxes, and Parkers and other doubles. Their presence is so consistent in factory double gun muzzles that if I see a muzzle without a keel I assume it has been shortened or a third party gunsmith has worked on it. I may be wrong about how ubiquitous and consistent they are in original muzzles. But I don't own a single double that doesn't have them.
