Use it on both and see my other thread on pa45 and pa145 on my tachihara. Both work. In summary, if you can find the larger film/paper (with 45 or 4x5 in its name), I would suggest pa45 is better. But I did use pa145 for 6 years now and is good for exposure.

Both did not need international back but work like a film holder.
