Beclere Model P3 "Monomite" Vacuum Tube Hearing Aid
The Beclere Model P3 "Monomite" vacuum tube hearing aid was
manufactured by Beclere Co. Ltd. of Oxford, England in 1950.
Sporting a shiny chrome case, the Beclere "Monomite" weighed a hefty
6¾ oz. without batteries. It measured 3⅜" x 2½" x ⅞" thick.
The microphone grill consisted of 2 vertical slots—one on each side
of the name (upper right).

The receiver cord had a three-pronged plug with one outside
prong larger than the others (left prong) so it could only be plugged in
one way. The right jack hole was also correspondingly larger. |

The Beclere Model P3 "Monomite" hearing aid used a "standard" custom
ear mold (left) that snapped on to the nubbin in the center of the
receiver (right).
The inscription on the receiver reads: "Lic'd by Brush Crystal
Crystals Ld." and then gives patent information.
