The serial number is 67-20339, with 67-0339 painted on the tail as per USAF instructions. The 1967 fiscal year makes this AQM-34V most likely a rebuilt older example. The last four of the serial number are repeated on many components. I'm not sure what the cut-out under the fuselage is meant for. Possibly the bracket there is meant for the attachment of a RATO bottle for ground launch?
