These early models were built entirely from photographs.  Yet most were scaled quite accurately, albeit lacking the "fine scale detailing" which today's modelers have come to expect.  Notice this Big Boy has only two hatch covers atop the Big Boy's sand domes.  This was because the builder only had SIDE VIEW photos to work from!  How could he have known the hatch covers were in pairs.  Also the tender truck pedestal side-frames are 'hollowed out' and made of copper.  The builder would make a single side frame pattern.  This would be pressed into a substance like our modeling clay which was then painted with an electrically conductive paint, placed in a plating tank, and plated with copper.  Thus the nicely detailed replica of the original was made, some time before the  'Lost Wax' process began to be employed.  Later hand built Big Boys did not use this process.

Every axle on both the loco and tender is sprung.  A lot of extra handwork for sure, and process that did not last long because of all the work.   Steel dies were created which allowed some of the parts to be 'coined'.  However, because of the prohibitively expensive cost of the dies, they were used only for parts that could be used on many models.  This model has coined driver centers, but only one style.  Added to those are hand filed counterweights.  

This model is very rare (1 of a kind) and unique for the great skill that went into building it.  One of the finest models we have seen pass through our shop!
