Ithaca Flues double

[burnt45]

Hey guys,

I've got this Ithaca 20ga double... I believe circa 1920's... and I'm trying to figure out the chokes.

It's got a "4" stamped under the left-side chamber, and a "0" under the right-side.

Am I correct to assume: Left = Full, Right = Improved?

Thanks!

4 should be full and 0 should be cylinder you'd think.

My ithaca is 4/2 and is full/mod.
