A late 19th or early 20th coil activated ringer, “Westen Telephone Construction Company, Chicago IL.” 5 x 6 x 5.5 tall with two bells mounted on top of a finger-jointed box. The bell-mounted lid is hinged with a hook-clasp and when opened shows the internal coils wound with green wire and mounted on a copper/gold painted cast frame, with adjustments to the clapper and one magnet. The three external terminals are mounted on what appears to be adjustable plates (?) and there are adjustment plates for each bell to placed a given distance from the clapper.
An interesting post-telegraph ringer box, very well made.
