I counted them up - three early UP Challengers, plus one each D&H and NP. Four Jabelmann Challengers, not counting a display boiler/frame/tender setup so folks can see where they start. And best of all, I guess, a Big Boy made exclusively of Lobaugh parts (well, the firebox and sand domes are different, and those neat coolers are PSC):
On this one, even the tender sides are Lobaugh. See those ripples? In the 1950s, Al Ellis thought that anything that needed bending should be annealed. So these gorgeous photo-etched sides are dead soft, and can be dented by picking the thing off the tracks. I usually make my own out of half-hard brass.
