T92 and T93 heavy self propelled guns

[Abraham Gubler]

I’m looking for any further information and/or imagery (especially a plan/side/front schematic) of the US Army’s HMC T92 and GMC T93 heavy self propelled guns (Gun or Howitzer Motor Carriage) from the end of WW2. Both were mounted on the chassis of the T26E3 heavy tank with the T92 mounting a M1 240mm howitzer and the T93 a M1 203mm L50 gun. 144 T92s were ordered before the end of the war but surrender of Japan saw the contract terminated after five were built.

Some technical data and more images are here: http://www.battletanks.com/t92_sp_240mm.htm
