Jeff,
Maybe early '60s. Someone on the list will know when. The pressure systems
used a pressure metal tank and a small air compressor vice pump. Close the
fittings and valves, put water in the tank, turn on the compressor, and see
if it will build up pressure sufficient to flow water at an adequate rate.
