Herb,
Good points! I notice also (not that it means much) that when it had two pumps, they were not spaced normally, the front pump is farther forward than usual. In the picture I posted it also still has the orriginal 1881 Baldwin smokebox door which I believe was the only one left at this late date.
These box headlights are much larger than the one Bachmann depicted. It fills up the whole platform while the Bachmann one does not. I may have to scratch build one. What is going on with or what is the point of the square extension on the front of the headlight? I've noticed that some of them seem to slope out (forward) at the top.
