Anyone ever hear of Bolivar Speaker Works?

Anyone know anything about a company named 'Bolivar Speaker Works' out of Tennessee? I came across a pair of what appeared to me to be well constructed, 3-way speakers (e.g., independent level adjustment on back for bass and midrange output; design of cabinet resembled the smaller Dahlquist speakers (sorry don't remember model #) from years back), but don't remember ever reading/hearing about the Bolivar company. Anyone know when they where in business and if the company made a good product? Just curious about this piece of audio history. Thanks.
