In the past I've seen a circa 1963 ad for a "G.E." tranzistoried camera - it was a big camera, but I think they could made some smaller versions too.

The image orthicon tube was quite big (15 inches / 38 cm long), except for slightly smaller experimental / military specials, which I doubt this production company would have. So, the camera head would be the size of a suitcase even if the circuits were transistorized.
