The portable was a brand new projector in 1932. It satisfied all the smaller theaters all over the country. They were less in price and affordable for a touring showman. Country halls, hospitals and even on board cruise ships such as the P&O ships that sailed the Pacific.
Calling it a portable was a bit of a misnomer they came in two heavy boxes which contained speaker and amplifiers.
The Jones family of Busselton had a normal theater but a big circuit of portable shows, Bridgetown, Ballingup, Margret River etc. The sons of the family still carry on the Drive-in at Busselton, and had a P5 and P 6
