The simple question is " was there actually a plain Toyo View 45G?"
My camera only list identifies it as a "45G" and the Toyo web site lists "45GII" and "45GX". This camera seems to have all the listed functions of the "45GII" but it's not marked that way. I'm pretty sure it is not the "45GX" because I don't have anything looking like a "Depth of Field Calculator Knob in 1/3 steps" and can someone explain what a "Bi-Axial Yaw Free Base Tilt" is? these are apparently the only two differences in the two models. Unfortunately, the Toyo web site is lacking in quality images of their products and I can't get a good look at one to figure it out for myself.
