In 1930 a batch of ten JF class tankers were built for Wiluna Gold mines by Hurst Nelson & Co. They were numbered 201-210 and were followed by two more in 1933 (211 and 212). The WAGR outline diagram is shown below.

In 1951 202, 203, 204, 208, 209, 210, 211 were sold to C.O.R. (later B.P.) and renumbered 79-85.

Number 207 was sold to Anglo-Westralian Mining in 1956 and in 1960 this tanker passed to H.C. Sleigh later CALTEX. CALTEX had also acquired 201, 205, 206 and 212 in 1951 but they were written off in 1971. In 1983 number 201 was resurrected by Westrail as JFS1287 but was finally written off in 1993. JF205 went to South Australian in 1971 as NTOE 1770 on the CR.

In 1936 the Lake View and Star Gold Mine bought another six numbered 132-137. In 1973 numbers 132-137 passed to SHELL. In 1987 number 134 was reclassified JFR.
