70cm is the longest bbl.'s originally fitted to those guns. And at one time they were the smallest framed 20 ga. O/U's made. Fun guns in that respect, but as Ted mentions, not so much for extended shooting.. but a delight to carry.

Hope it provides you w/much pleasure, JC. They were never common guns even when Beretta was making them. I want to say they stopped making them around 1964, but as Russ used to say, I could be wrong.
