20,000 gallon elevated water tank and stand (without alkalinity plant).  This type of tank was quite common - examples could be found at Penrith, Boorowa, Martin's Creek, Griffith, Barraba, Mungindi, Cootamundra and many other locations.  The example at Telegraph Point remains.
The kit contains brass and nickel silver etches, epoxy castings, 3d printed parts and wire to assemble an accurate model of this piece of essential NSWGR-era infrastructure.
