My one and only Ittaker is a Grade 3 Super Ten that i purchased through a classified ad here a couple years ago. I've been very pleased with it so far.

Super 10's are great guns. Stan, yours looks like a nice one! Thanks for using the term "Ittaker" which I heard so often from old timers when I was a kid out for small game and while hunting with my Ithaca/Western Arms double with a good fox hunter in town who took me under his wing. The term sure brings back some memories. :)

I've shot many Super 10's for pattern testing and while hunting with 1-5/8 ounce/2-7/8" shells that simulated the heaviest period loadings, and with nary a problem to include the barrel ribs and forend lug. :)

This is just evidence that you can shoot; WELL! That's impressive.
They are fun guns too.

And here’s a Crass from 1892. EVERY transaction in life is a trade off as to do you want the money or said object of desire. This one, yes, the barrels have been cut, and it doesn’t have much value, but the price as purchased off this very forum was low enough that I can say that this nice condition Ithaca is far more desirable than the $450 it took to get to my doorstep. Even if only as a wallhanger but Sherman Bell has proven it’s probably okay to shoot.

I have a 410 Ithaca that I picked up for short money. Had Ryan Cullity strip and oil finish the stock as the original finish was crazed and ugly. Came out very well. Ithaca put nice wood on these early sxs's

The early NID period Ithaca Gun Co. catalogs state the stocks and forearms were "oil finish."

By 1929 Ithaca Gun Co. catalogs "oil" is gone replaced with "highly", "finely" etc.
