ALCO 4000 series steam locomotive

Where can I get detailed information regarding all of the ALCO 4000 series that were sold to the B&M railroad? Thanks for the help (I am trying to track down the train that used to carry the bell that I own).

The Boston and Maine railroads 4000 series engines were built by Lima (4000-4024) and Baldwin (4100-4117) Not Alco.
