I have a very late H grade on which the SN's on both frame & barrels have been over stamped. @ # 73,138 & # 73142 though they got them 4 numbers apart. SN's on other parts match one of the two numbers, but offhand I forget which. Quite certain this is an Ithaca assembled gun. Has twist barrels & only weighs 6˝ lbs, 12 ga-28". Also is fitted with an Infallible SST, quite possibly done when new by Ithaca.
Damascus barrels were available on the G grade all the way up to the end, not really unusual to find them. The 20ga though is most often found in the DS grade. The higher the grade the less common it is to find a 20.
