A mid century 1960s nutcracker, by Inca/Norsard, Switzerland. It's the AF23 model, made of cast aluminium. Very much an atomic/space age feel with its wings and funky design.
Stands a minimum of 11cm tall x 6cm wide x 4cm deep (14.5cm when extended). Will press a nut up to about 4x3.5cm using its steel screw-down corkscrew presser. 
Very good condition - these tarnish very easily and this is a good example compared to many - see photos. A lovely brushed silver grey colour. A fab retro addition to any mid-century kitchen/bar area.
