Photographic print, black & white, solar heater model for heating of boiler feed water, constructed by Lawrence Hargrave 1907-1909, taken at Deutsches Museum, Munich, Germany, prior to 1944-45, copy print made in 1960
Hargrave donated models to the Deutsches Museum in 1909, following his unsuccessful attempts to find an institution in Australia, England, USA and France who might take them. Most of the models were destroyed in the Allied bombing of Munich during World War II. Those that survived were transferred to the Museum of Applied Arts and Sciences [later Powerhouse Museum] in 1960 and 1966. This model, bearing the Deutsches Museum object number 23386, is now held by the Powerhouse Museum at B1431.

Hargrave, Sydney' and a typed label with the translation of this caption 'PHOTO NO. 4405. SUN KETTLE FOR THE HEATING OF KETTLE FEEDING WATER. BY: L. HARGRAVE, SYDNEY.'
