Agreed on the weight.
Rather than this Ithaca, I had previously chosen the
Parker"Super 12"-rare as they were by Parker Bros.
This Parker graces the cover of the Winter 2021 issue of P Pages.

I have original 1939 Dealer/Jobber catalogs from Remington-Parker.
In their catalogs, R-Parker state that they will chamber to any
12 gauge chambering , including 3 inch, for Grades GH and above, at no additional charge.
I also think they offered that for VH grade guns, though not stated, also at no extra charge-which translates to all graded Parkers.
It seems that graded 3 in-2 7/8 in Remington-Parkers are just about as rare as the guns built by Parker Bros. A puzzlement
answered by the Depression, new Federal waterfowl game laws, and the droughts in Canada during the 1930s.
