Precise reproduction french glass diaphragms

After
almost two years of inquiring and testing, I am proud to announce the
availability of new french glass diaphragms for early cylinder
reproducers and recorders:
Newly engineered French glass
diaphragms for early phonograph reproducers and recorders - made of
high quality thin glass all manufactured to the old specifications,
each precisely and smoothly cut. Now also available for Victor
Exhibition reprocuders!
The vast majority of early phonograph reproducers and recorders from
the 1890s are discovered with broken or missing glass diaphragms. In
some cases restoration is even impossible without destroying the old
glass diaphragm. Because of the extreme rarity of expensive, old glass
stock, many restorations are made using mica diaphragms. Due to
its unique acoustical characteristics, both in recording and in
playback, only glass provides a truly authentic and original sound.
Place the diaphragm between the two existing rubber gaskets and just
apply some crazy glue or a drop of shellac to the middle of the
diaphragm to attach the link carriage (Edison), stylus bar or recording
stylus (Columbia).
