Mason Bogie Project in 1:20.3

This is my current Mason Bogie Project in 1:20.3 scale, and is the prototype model for the Masterclass 2002 series at the mylargescale.com web site. The model represents DSP&P #42, as repainted and relettered by the Union Pacific owners in 1885. The #42 was formerly DSP&P #6, 'Tenmile', built in 1878. The unfinished paint scheme represents UP specfications for 1885. For more about Mason building and the history of the Mason Bogie, do visit the Masterclass sometime!
