For $75 US, the only way you could have acquired all that stuff cheaper would be with a mask and a gun.....

I believe the ektamatic processor made "stabilization prints." These were made on very thin paper and were about one step above printing out paper. Their chief function (I believe) was to provide a photographic print that could be converted into a negative by a process camera. The only place I've seen one is in an offset printing plant.

Kostiner was an "archival" print /film washer like the Zone VI, gravity works, etc., etc
