Re: Parts swapping question

I'd like to know how 283 managed to survive with what appeared to be the original Baldwin lap seam wrought iron boiler. Every other C-16 that survived in service part around 1916 had a new boiler applied. When the new boilers were applied, I don't think they had any builder's plates. Then number on original builder's plate would refer to the original boiler, not the replacement one. The information about 42 and 283 swapping boilers, refers to something that happened early in the history of the two locomotives. In order for Best to notice this info, 283 had to have it's original builder's plate on the smokebox. I don't think they put old builder's plates on re-boilered engines. Or did they, occasionally?
