Ithaca Lewis Model
 

Anyone have any idea what these numbers under the extractor on a Lewis Model Ithaca mean?

Boy, if you are asking us, it really must be a mystery. That's the kind of question we would ask you, ie, I am clueless. Barrels look a little rough, hope they clean up.

They could be chokes. A "3" was IM. Could also be the number of the person that inspected the barrel. Alot of the numbers are a mystery. Although most barrel marks should be on the flats or just in front of them.

A guess: Maybe they are the last two digits of pellet counts, like how Rem. 1894s are stamped?

Jeffery I thought the same thing. That’s how my Remington DEO’s are marked. Only they are marked on the barrel flats.

The gun was posted on shotgunworld.com and I certainly didn't know an answer, so I brought it over here. A lot more shotgun knowledge on the PGCA site than other boards around the internet. When it comes to Ithaca doubles I'm primarily an NID guy. From what I've observed Ithaca started their zero to four choke markings on the front of the barrel flats at about 200000 in the Flues era. Sometimes they marked the chokes as a fraction --

but usually just the numerator --

I haven't spent any time looking under the extractors/ejectors of earlier Ithaca doubles, so don't know if others have numbers stamped there. I kind of like the idea of Remington like pellet count but taking the extractor out and stamping a number after you've fired the gun and counted the pattern seems pretty labor intensive.

Another guess: How about the chokes in thousandths?

Do you know John Eurom to ask him?

Where is it on shotgunworld?
