110mm T203 and 156mm T202 howitzers

[A Tentative Fleet Plan]

I stumbled across these weapons in Hunnicutt's Sheridan, these weapons being intended for, respectively, the T195 and T196 Self-Propelled Guns (later to enter service with 105mm and 155mm Howitzers as the M108 and M109).

Does anyone have anymore information on these weapons?
