Dave, when time allows I will sift through Walts book and see if there is any mention of those stamps. I will also hava a look at my examples of Crass, Lewis, Minier models.

I just got home(11:30PM EST). I pulled numerous Ithaca doubles(Crass, Lewis, Minier, & Flues) from the rack. Serial numbers ranged from Crass #37xxx through Flues 377xxx. All Flues models with a choke designation stamped on the barrel flats have no stamps under the extractor. All models (Crass-Flues) with no choke designation have numbers under the extractor. The last Flues I have without choke marks is 1879xx, the first with marks(4/4 &4/4) is 202xxx.
That said, I can not make any correlation between these numbers and anything relative to chokes. Some of the guns are four digits with two on the left and two on the right. Others are three digits with two left and one right. One gun has two left but only one on the right. NIG 487xx has four digits, all on the left. I believe there is more study to be done.
During this exercise of observation I also noticed several of the barrel lugs were also stamped on the rear face of the lug with an X or R. There is much yet to decipher.
