of combat. A single M2, .50 cal mounted on a M4-style pipe stand tended to appear, disappear, and move around from scene to scene on the forward deck. Normally, the forward gun would have been an either an M2 .50 cal. heavy machine gun or Oerlikon 20-mm antiaircraft cannon on a pedestal to the right of centerline, back nearer the charthouse and possibly a 37-mm Browning aircraft cannon or a 37-mm M3 Army antitank gun strapped or bolted to the deck forward (as had been thought the case for the PT-109). A pseudo-"radar" unit and mast was added aft of midhull, where normally an Mk-4 Oerlikon 20-mm single antiaircraft cannon was mounted. The mast on the -73'''s command-bridge was also incorrect. The 40-mm Bofors cannon or pedestal-mounted Oerlikon 20-mm antiaircraft cannon usually found on the aft deck was done away with completely, as was one of the engine compartment ventilator housings and the M2 smoke screen generator. Two mock-ups of US Navy 21" MK-18, swing-out, torpedo tubes (as carried on the early war 80-ft Elco boats like the PT-109) replacing the MK-7/8 tubes normally carried by the Vosper 71-ft. The gunwale side cut-outs normally seen on the Vosper, were built-up forward of the cabin, creating a flush forward deck. Normally, the Vosper required forward clearance in front of the Mk 7/8 tubes when torpedoes were fired over the gunwale. Shots of the crew aboard the PT-73 were usually staged on a full-scale mock-up of the bridge and gun tubs in front of a front projection screen at Universal. PT-73s final appearance (one of the two converted 63-ft boats) was in the 1970s show Emergency! ("Quicker Than the Eye", season 4, episode 8, aired: 11/9 1974). Station 51 was dispatched to a movie studio to rescue a man trapped beneath a boat. The boat in question was being moved from one end of the studio to another by truck, and wooden supports holding it had broken and trapped a man underneath. "PT-73" is visible on the bow, appearing as if the numbers had been removed, but an image of them remained. The boat was missing the pilot house, masts, and depth charges. No record of the final fate of this boat, or the other converted 63-ft boat has been found. The sea-going (ex-Howard Hughes PT-694 boat) PT-73 was sold to the mayor of Hawthorne, California, Hal Crozer, and converted to a
