Difference between Toyo 45A and 45AII/AX ?

I have seen a used Toyo 45A at a photo shop. At the Toyo Homepage I
found only specifications for the 45AII and 45AX, but nothing about the
older 45A. Who can tell me the difference between the types, what about
the movements, especially for wide angle? When has the 45A been
discontinued?

In the specifications for 45AII and 45AX I see:
Manual front rise 41 mm 45AII
Rise/fall 20.5/23.5 mm 45AX
Shift Bed 40+40 mm 45AX
Does that mean that the 45AII has a front rise +41mm while +/-20.5/23.5
at 45AX? Is there a additionel +/- 40 mm front shift at the 45AX?
This specifications are a little bit confusing.

Thanks for your help

The differences in the 45AII and 45AX (and the 45A) are:

1. 45AII has a revolving back and the AX does not (can be added to the AX)
2. 45AII has a folding focusing hood. AX does not (can be added)

Front rise is 20.5mm
Front fall is 23.5mm
Shift is 7+7 (means 7mm each way)
Tilt is 90 degrees down and 15 degrees back
Swing is 8 + 8 degrees (8 degrees each way)
Rear body tilt is the same (90 degrees down & 15 degrees back)
Rear swing is 8 + 8 degrees

More rise can be achieved by pointing camera up and squaring front and rear
standards. More fall can be added with the same mehtod but it is limited as 15
degrees is the max back tilt.

I've only used a 90mm wide angle so far. The bellows is fine for this. I have
movements, there's no uncomfortable binding on the bellows and I can use a
flat lensboard. A 75mm should be able to be used with a flat board but
probably with little or no movements - a recessed board may be better. A 65
would definitely require a recessed board. I don't know if anything wider can
be used or not (and, as I said, I haven't used the 75 or 65 personally so you
should make sure by renting one first or buying with an MBG).

I have the AX and it's an excellent solid camera. I would like to have more
rise/fall and more rear standard aft tilt but I've worked around it so far and
really like the camera. Nothing is ever perfect and this seems especially true
with cameras.

The Toyo 45AII has better knobs and a better finish than the
Toyo 45A.

The tothed rail for the focusing was plastic in the Toyo 45A, but it
is brass in the Toyo 45AII.

After my opinion the 45AII is a upgrade of the 45A with the troublesome
parts replaced by better materials and a better ergonomy.

I have a 65/5.6 on a flat lensboard with my 45AII, though no movement,
it can focuss to infinity. I think you can only use up to 47mm with
recess lensboard, not likely the Rodenstok 35/5.6.

I have the A2, I need to built two metal bars at each size so that it
looks like the hypotenus of a triangle. The reason I need the two bars
is because the body itself catch wind too easily at long time expose.
My Horseman 45FA (sold already) work much better to stop wind effect.
The revolving back is not much useful to me but it create weight and
thicker body, rather not useful to a hiker.

I've not seen the wind problem. However, except for hurricanes or other bad
weather, our winds tend to be reasonably mild - usually causing subject blur
instead of camera blur.

The revolving back is desirable on paper but I am glad I do not have it for
the reasons you described - size and weight. And, my folding focusing hood
seems to languish in the bag as it's easier to use a darkcloth without it
attached (especially the elastic edged Darkroom Innovations cloth).
