I bought a few US 'phones in a second-hand shop over here [1].
Given that the switch to IC-based tone generators looks to be around
1982, before the breakup of Ma Bell, I'd say that there are few phones
in thrift stores here of that vintage any more. Maybe at an estate
sale from someone who hasn't moved in 25 years.
If you have access to lift the faceplate, look for a part number
starting in '35' and a manufacturing date prior to 1982. You don't
want a part number starting with '72'.*
