Help ID-ing older hammer Ithaca 10 bore

[Milton Starr]

This is the sellers bore description



E BORES DOE HAVE SOME PITTING. IT DOES NOT LOOK LIKE THERE ARE ANY EXTREME PITTS, BUT THERE IS A FAIR AMOUNT OF IT. IT LOOKS AS IF IT COULD BE HONED OUT TO A LARGE EXTENT. I BELIEVE THAT THE BARRELS ARE THICK ENOUGH FOR IT TO BE OF LITTLE CONSEQUENCE AS FAR AS STRENGTH IS CONCERNED. IF I WERE GOING TO USE IT FOR A SHOOTER MYSELF, I WULD LEAVE THEM ALONE

-- Milton- for what's it worth in passing- honing any ID cylinder even with a pilot to allow for "out of round" can have its hazards- but the laps of iron and steel forge welded to make these older barrels- rather than the continuous metallurgy of a lathe turned proof steel barrel from a blank- I'll defer to others who have worked with Twist/Damascus barrels, but remember this- older BP shells developed their greatest pressure curve in the initial breech area- later smokeless shotgun powders have lengthened that pressure curve somewhat-the RST engineers have really been a asset to those of us who enjoy shooting the older fine doubles, no matter the gauge- Pitting can cause a barrel to fail in that area, just as a slag inclusion can cause a weldment to fail under load stresses. FYI!!
