Colombamike: thank you for your comment and i fix some problems, HTMS Thonburi version 1938 on page 23
my ships base on photos, video clips and HTMS Thonburi memorial. underwaterhull base on RTN ship plan and RTN ship model. 1961 photos is HTMS Thonburi (ธนบุรี), after decommissioned she came to patrol squdron command center and i don't know when she was officially struck. small aft rangefinder i'm not sure but docoment say its armed. and Thonburi class armed 200 mm guns.
this is 40/40 mm gun for HTMS Sri Ayudhya (ศรีอยุธยา) (my part very ugly), this photo show 2 single 75/51mm bofors guns.
