Thank you for this interesting history. The post you are
replying to has not yet showed up on the list here.
I have three Vibroplex keys, one made in 1920, with the old
type hinge for dashes, one made in 1944, which appears to have
been made with re-worked parts, and one made in 1961. The 1944
key in in a case which originally had the owner's name marked but
that has long since worn off and I never recorded it. My mom
bought it in a thrift shop. She must have recognized what it was
from the Bunnell J-36 I used on the air at the time because whe
was not a technical person. She was remarkable. These are all
"original" models.
