Help with film holder for old 8x10 camera

[someone_else]

I recently got an old wooden 8x10 camera - with no marking on it to identify the manufacturer - which came without holders. Based on the dimensions below (which are all in mm) could anyone help me identify some suitable holders? Unfortunately this camera doesn't have the sandwich type of design that would allow me to use modern holders - it seems that the holder was expected to slot in and be held in place with some small protruding metal grips - but I am hoping that it might use some old standard.

Terribly sorry for the poorly marked dimensions (which by the way are meant to show the whole area of the holder) - it's hard to draw things on a phone.

It looks to be made for an old "book type" holder although I could be wrong.
