Incredibly large and detailed 34" long hard plastic gun ©1964 Mattel Inc. Comes with original box, which has obvious wear and aging with scattered creases and tears. VG. Gun is nicely detailed and includes scope and simulated features marked "Breech Lot, Test Port, Sonic Output, Vortex Output." One side of gun has large "Zero M" sticker. Tiny corner tip off of this sticker. Top of gun is designed with priming bolt and large air-loader handle designed to fill the gun with air that was then compressed and when trigger was pulled large and very loud blast of air is fired. Box reads "Fires Booming Bolts Of Sonic Power/Affective Range Up To 40 Feet." Comes with several die-cut cardboard target pieces, one still attached to box. Pieces have some aging but are Fine. Gun worked when we first tested it but this is no longer the case. Still an Exc. display. Easily the nicest piece in the Mattel Agent Zero M line and one of the most impressive toy guns ever produced. Rare and only the second example we've been able to offer.
