Arthur:
I don't remember those, but I remember 1A2 sets that looked identical to ComKey 416 sets that were made by TPI (TelePath Industries in Roanoke, VA). I believe that they were associated with Valcom as some point.
They did not have the DSS key field, but otherwise, they looked identical. Perhaps more similar to a MET. The dial had speed dialing functions, as well as redial.
