bob...I don't believe there was ever a Beretta Model 408. The absense of engraving on the receiver makes me think this is a 409. Oddly, I did google "Beretta Model 408" and found 2 other references to guys saying that 408 appears on their forend. I'm at a loss. Likewise with the third bite on this gun...however, the Greener crossbolt is pretty common.
