comments by Walt Snyder, the Ithaca historian and author of the books on Ithacas suggests that the barrel had it choke changed at the factory. There are factory servicepeople identification marks at the end of the barrel, the letters saying MOD have the correct, height, spacing, layout and placement as original MOD stampings do. The original FULL was carefully blanked out with a small rectangle area and the word MOD substituted. With the facts about the inspector/repairman marks, it is highly probable it is still a 100% factory gun.
The stamping is so precise, it would have been hard to stamp by hand.
That's a very pretty little lady there with some great figured wood... er... that just sounded wrong!
Were you listening to that old song by the Kinks "Lola" before you wrote up that line ????
