Furness 115 Class Baltic Tank in a variety of scales
 
It comes with it's detail pack in each order, buffers, cab roof, smokebox door etc.
 
Like most loco's a 3D printed chassis and bogies etc has been designed and was uploaded to Shpeways.  They can be printed here although they arn't as good as the Shapeways ones, until metal ones are available they can be printed although they are only supposed to be a stop-gap until more robust engineering results are made.
 
The beautiful red one is a 2.54mm TT 120 scale print compelted by Garry Hall, he modified the inside and buffer beams slightly to accomodate a Hornby TT chassis.  The grey one with a chassis is Garry Hall's example before being completed and the two pictures without a chassis is a 4mm / 00/EM/P4 example without it's detail pack on show.
