WOW! She has really changed. Note the Slide valves, Twin 9.5" air pumps, Spoked pilot wheels, And the round number board on the smokebox without numbers on the headlight. The Box headlight is electric, An the classification lamps are the Radial type, and they have been electrified, Most were changed over by removing the chimney and a flat plate added to hold the lamp, these have the power cord comming thru the top of the chimney.
And it looks to me to be a 5 chime whistle, I wonder where that went?
