    ATA-173 426k ATR-100 running acceptance trials at Port Arthur, TX,, early 1944. Note the name board mounted on the bridge deck shield aft of the bridge. “ATR-100” but no hull number on the bow. Note also the mounting of a 20mm gun on the bridge wing (with “monkey bars” which prevented a free swinging of the mount all the way aft and the mast yardarms. This photo was edited to eliminate the radar and the TBS antennas. Also of note is the elongated 01 deck house aft of the bridge deck which was common on Army LT’s and British lead lease BAT’s but not Navy ATA types. James Swank
