Text from Karl: The two b&w ones are 1979,
myself, Phil Bosch, and Al Gour (ID from Phil Bosch), with a SL2800 box coater for a German customer
The three color pictures are also in
1979; Phil Bosch with the substrate holder for a SL2800 horizontal drum system for
Ebauches/ETA Switzerland, one of the Swiss customers at his out-doors work desk in the back yard of the systems department, and finally Phil and another Swiss at lunch break in the same back yard (note the empty six pack of Michelob!).
