Grundig Reporter 700L and EN3 notebook

Anyone got any data on either of these? The 700L is I think the 1st or 2nd Grundig R2R machine, and is certainly rather different to any other Grundig I've ever come across! It's actually currently (19 Feb 2014) the heading picture in the "Library" button above.
The EN3 is a little hand-held battery dictation recorder/player. Nice tidy little unit.
