Found 6,5x9 cm sheet/cut film holder

I am looking for 6,5x9 cm cut film holder that would fit an International Graflex 23 system, perhaps like an Orwo NP-22 6,5c9 cm holder.
Mamiya (Press?) has a cut film holder too which, I think, would fit, but I don't know the type reference.

It has to fit the Silvestri SLV, and I know that the famous Linhof Cassette will not fit as too thick.

Look at the photo to see what I mean:

​

These all have the same dimensions except for film size so you can use either.

A horseman 8 or 10 will fit no problem?
The silvestri doesn't have an option for a springback?(to hold a cut film holder)
6.5x9 is the same as standard graflock 23(2 1/4×3 1/4)?( roberts camera on ebay had many listed not too long ago)
Not the cut film holders for old voigtlanders(I think)?

I have two roll film holders, but I want a few sheet film holders too, there are some out there, like from Mamiya for their 6x9 Press camera, but I don't know if the type 'A' or the 'J' would fit...
Or perhaps the ones as in this photo?
I simply don't know (yet).

RB67 cut film holders are what you need. 6.5x9 will fit in either A or J without the film sheath. I’d personally go for type A though, as you can use the film sheath with instax film.
