Nice finds, congratulations!!

Do you have a picture of the base on the '51? A valuable phone could be hiding under those later plastics. Could the '51' be a stamp for -51 (WE color code for green)?

The 440 sure is different.  I don't think I've seen one quite like it before.  The dial makes me think it may have been made by Western Electric (at&t).  The configuration of the dial is right for that particular make.

The 440 is a Northern Telecom 'Dawn' phone.  See Imagination Telephones by Northern Telecom on paul-f's site.

It looks like a 1975 500. Someone probably stamped '51' or '-51' on the base, to signify that it's a green phone. It also has some 1960s dates, which I'm not surprised about,

Again, good haul!
