. Primus 1003 (W) Massive 3 litre tank, works like a dream but the big tank needs about 100+ pumps to get enoght of pressure. SL! Jukka
These large tank lamps were often used in poultry sheds in the winter. The heat and light fooled the birds and kept them in egg laying mode. For more information on this lamp, check out the Primus 1934 advert, which is shown on this website. Jeff.
