Polish airspeed indicator and the Story of Warsaw Instrument Works Added
A Polish PZL PR-250S airspeed indicator joins the collection, together with a new historical feature on PZL and the Warsaw instrument works on Grochowska Street.
The collection has been expanded with a Polish PZL PR-250S aviation airspeed indicator, manufactured in 1978 and intended primarily for gliders and light aircraft. The instrument measures indicated airspeed from the difference between total and static pressure and has a range of 50–250 km/h.
