In mid 1944 it was lengthened to 65 calibers to reach the magic 3000 ft/sec velocity figure and proposals for putting it on a wheeled carriage appeared. Development countined through 1945. It fired a 39lb (17.7kg) AP shell at 3100 ft/sec (945 m/sec) and the penetration was claimed as 210 mm @ 1000 yards @ 0 deg"   Interesting info on the T5.   So we have the following   T5 (tank) 48 calibers in length T8 (towed) 65 calibers in length T5E1 (tank) 65 calibers in length T5E2 (tank) 65 calibers in length   A 39lb shell would be the T32 round I imagine as it was the same weight, 3100 f/s is 100 f/s more then what hunnicutt lists.   Chief ever found any info on that short T5 48 caliber 105mm? sounds like it would be an interesting weapon option for T6 tanks.
