Ok so I finally got to take pictures of the different plate holders I have. As it turns out. There are 8 different types of holders!
I have two holders that should fit a zeiss/ica maximar but I'm keeping them since they also fit my voigtländer avus. Interestingly enough they don't fit my linhof technika II (they wiggle too much) although they are almost identical to the recomar holders that I'm looking for (the recomar holders also fit the avus).
Except for the Zeiss/ica ideal holders I have no idea which cameras these holders might fit.
None of them come with film sheaths by the way.
I don't know the correct term for the thin part at the edge of the holders so I've choosen to call it "groove", even though the term might not be correct.
First of are three holders with the following dimensions (these seem identical to the holders Ian Grant says will fit a rodenstock and orian plate camera) :
Length: 139mm
width: 100mm
locating lip: 2mm
"groove": 2mm

Then there are elleven holders without any locating lip. These holders seem Identical to the holders Ian Grant says will fit early linhof cameras except, they don't at all fit my linhof Technika II.
Length: 140mm
width: 100mm

Last but not least I have a total of fourteen holders that will fit the Zeiss/Ica ideal (and the Juwel but that is a very very rare camera). (eight of them are good four are usable and the last too are very very rusty) These are currently spoken for but I'll show a picture of one anyway.
