I had steel boiler made (not copper), bought 2 injectors vs. axle pump, and purchased oiler, blowdown valves, sight glass, etc. Purchased a tender body (not the slant back). Horn made from a kit. Tender trucks and couplers from Tom Bee.Driver and cylinder castings from Friends. Loco weighs about 150 lbs.
