Thanks To both Aman, and  Barbara  on different lists, for your helpful notes.
Thanks to patient help on the phone from one of you/(helps so much to be told how and where to navigate to find what's necessary,) and reading help from my sighted wife,  to describe what and where's on the screen,
we've learned that this indeed is a "C E D A/Cedar, , or "Snap" phone, and is indeed useable with screen reader software.  
so getting it for $20 is a bargain.  Thanks, all, Danny.
