I cannot see how you can make that statement since the Rolleicord Va and Vb have their focussing knobs on the same side of the camera body (on the left) as does the Rolleiflex T. So their user controls are identical i.e. focussing knob on the left and advance (knob for cord, lever for T) on the right. :think:
Even for earlier models up to and including the V, had their focussing and winding knob on the right side of the camera (the same side as the advance knob), hardly a good setup for lefties.
The only other advantage the T has over the cords is that the Rolleiflex T's lever wind automatically cocks the shutter, while you have to manually charge the shutter on the cords.
