AFV Profile 22, "Panzerkampfwagen 38(t) and 35(t)" by John Milsom: In 1943/43 the Heereswaffenamt gave Skoda specifications for a 10.5 ton reconnaissance tank and a 22 ton tank. They were to use components from the TNHP-S and have a speed of up to 38mph with a new steering system developed by Skoda. They were to have sloped armor, and the armament of the T25 was to be a 75mm gun with a muzzle velocity of 2920 ft/sec with semi-automatic loading from a circular drum magazine under the floor. Bore evacuation was by compressed air and spent cartridges were to be disposed of via a hatch in the floor. Turret traverse was to be electro-hydraulic. No prototype was ever built, but there was a proposal to carry the le.FH43 Skoda 10.5 cm L/30 howitzer and a coaxial MG in a fully traversable, dismountable turret under the designation Heuschrecke 10. With a 5 men crew and 60 rounds of 10.5cm ammo, the estimated weight was 24 tons, and the armor was to be 30mm front, 20mm sides, 10mm rear, and 30-10mm on turret.
Drawing of the T25, which is labelled as being from the Milsom Collection, shows a tank with a low track, somewhat reminiscent of the T34, with 6 roadwheels a side and no return rollers. The rather high hull sides extend over the tracks and is sloped slightly (maybe 15-20 degrees from vertical). The hull front is sloped at about 45 degrees. The turret is mounted forward as in T34, and appears to have very little rear overhang (looks sort of like the Panther schmal Turm from the side) but the frontal view shows that the turret has a wide frontal plate that is almost vertical. The gun mantlet appears to be circular (sort of Saukopf without the "snout"). From the vision slits in the hull, it looks like there are two crew members in front, but no hull machine gun, so presumably the second crew is assistant driver and/or wireless operator. The length of the hull is 6185mm, width 2750mm, height to top of turret hatch 2765mm.
