A rare WW1 Italian aircraft altimeter by Officine Agolini Parma.
Circa - 1917.
In good original condition, retaining the correct outer leather case with four
metal fixing rings - allowing the instrument to be fitted within a cockpit.
Originally a French system - connecting the case to a sprung cradle - alleviating
One outer strap has broken - the protective leather cover (also stamped by the maker)
has survived in loose condition. The interior lined with green velvet - another unnecessary
but fine addition to an instrument destined for aerial combat.
The instrument itself is in very good condition having a virtually unmarked outer nickel plated
brass case with clear-silvered dial and bevelled glass.
In working order, responding well to barometric pressure variations.
Correctly marked "Aviazione Militaire Italiana" proving its use with the Italian Military Air
Service during WW1.
As fitted to early Caprioni aeroplanes.
