Thanks for the info Richard.  I had a TAC bug and I agree that it seemed of
lesser quality than a typical Vibroplex of the time.  I sold mine (and kept
and use my Vibroplexen).

I have the remains of an old "Stream" key and it suffers from the failing
zinc casting. I think one trade name for this material is "Zamac"  ... a
generic term is pot metal.  It's possible for it to be long lived but
whoever made the stuff for the Stream sure didn't have the recipe.
