Clickety-Clack. Dont look back. Two additions since the family photo; 1939 M37 20 and 1942 37R 20 which are in the third and second photos along with the same M17. The close-ups are of the 1939 M37 20 showing its high gloss bluing of the earlier guns and the hand-chased engraving. The roller engraving set-up was initially faulty, rather than discard the receivers, the Ithaca shop engravers finished the engraving by hand so that the guns could be sold. Last photo is a close-up of the 20 ga. 1942 M37R's forend.
