Re: 'Little Yarra' locomotive.
Details of the specifications of Little Yarra, and drawings, were included in an article in Light Railways No.200, April 2008. It is available as a free PDF download from this webpage: https://lrrsa.org.au/Lrr_LRh.htm
There are quite a lot of photographs of Little Yarra in the LRRSA book Arsenic and Molasses. These show both sides of the loco at all stages of its life, and a number of them are full page illustrations.
It is worth noting that every reference to the major dimensions of Little Yarra published between 1915 and 2007 were wrong, and David Fletcher's drawing in Light Railways No.200 was the first to be based on correct dimensions.
