i've been looking for one of these for years, not to be mistaken for the later pressed steel, blue coloured models, this is an early issue all aluminium 'eiffel-tower/pilon' framed model. dual height adjustable, cast aluminium sections with plywood panels. one handle is broken off but still fully useable. purchased locally. i bet that Konstantin Grcic has one in his workshop.
great height for a chop saw
