Hi all,

While hunting for 10x15 cm holders for my great grandfather's 1920's Zeca field camera, I happened to come across a set of these:

There are nine of them. There's "BREVETE SGDG" stamped on the holders, so they are French and by the looks probably around WW2 or earlier. I don't know the manufacturer. They fit film exactly 90 mm wide but only about 115 mm long.

I'm likely selling them because I cannot foresee any use for them myself, but I'd like to know what exactly I'm selling. Is the format likely to be 9x12 cm?
