Earlier this evening I was looking for the Suttle Apparatus catalog.
A check of Suttle's website revealed that the company was acquired by Primex Technologies back in March of this year. The website is also devoid of any mention of legacy Bell System jacks.
Now an Internet search of some of those legacy jacks comes up with "Suttle Simplex".
Does this mean that Suttle's legacy telephone jacks were sold to Simplex...as in Simplex Grinnell?
