H M V Exhibition soundbox with a Resin Impregnated Silk diaphragm

Standard soundbox from the 1920’s. The later type made in the U.K with the more flexible triangular needle port to allow use of Bamboo fibre needles as well as Burmese Colour needles & steel types. This soundbox has a newly made Diaphragm from a natural resin Impregnated Silk from a high quality, Antique Japanese Kimono. the resin has been built up in layers & gives a tonal reproduction similar to a Mica diaphragm, but with a slightly softer tone.
