Plate Holder ID

I decided I should set to and load some sheet film holders, both 4x5" & 9x12cm DDS types and some older 9x12cm holders that fit my Zeh Zeca. Having a rummage through the camera cupboard, I came across these double sided plate holders, but these don't fit any camera I've got. They're a different outer dimension to the DDS holders which fit the MPP.

Anyone got any pointers to what they might fit?

They seem to be of the 10x15 cm size and would be the type used in Zeiss Palmos or Zeiss/Contessa-Nettel cameras with focal plane shutters. Also could fit old ICA / Zeiss SLR cameras.

I have identical holders, the same dimensions, just grabbed one from the garage, and it has a plate in it (processed). It's a 9x12 plate holder, but yours has an adapter in the last photo, I guess for v8x12b film. I have no idea what camera they fit,
