My dad attended the Expo in 1939 when he was in the Navy...he made a voice recording on an aluminum record...about the size of a modern day CD........the label on the record says to use a "cactus" or "fiber" needle to play it....but....unfortunately...someone has used one of the "old" steel needles to play it...does anyone know who or where I can have it restored??
Thank you,
