Stereo Glass Negatives

Today I had to decide between some home DIY or scanning some negatives…

So, here are some glass plate negatives from the boxes of treasure as promised. Its a mix of subject matter and formats. Mostly quarter plate and Magic Lantern negatives. I am unsure if they are copies or original negatives, some are mounted with some sort of glue and others by tape/stamps. Some emulsion side up and some down.

The adhesive has deteriorated on most.
The glass support of the negatives and supporting plate are quite thick in some examples.
This is quite distinctive, anyone have any ideas?

So a right mix, anybody have any thoughts then please do let me know.
