the table top rack unit, that also included the power supply (bottom). 

The 6 cavity duplexer is under the table 
along with an extra (light coloured) cavity filter. 

The object in the centre of the board on the wall at the back,
is a mains powered mechanical clock, that was used for many years

Note the white polystyrene used as insulation on the walls 
of the garden shed.
