[GreenKeys] What's A "Isophon Lautsprecher"?

[Merz Donald S]

Hmmm...What I have here is 2 small packages about 3 inches square and 1 =
inch deep. The label on each one says "Isophon Lautsprecher St HB 7  =
S228". Inside each package is a 1/2 inch thick bakelite and aluminum =
assembly with a grille on one side and 2 wires on the other. The label =
on the back of each of these is the same as on the package. Molded into =
the back of each one is "Made in Germany". Hmmm...it doesn't say "made =
in West Germany" and it is too old to be made in post-USSR-breakup =
Germany. So I conclude that these were made in pre-war Nazi Deutschland. =


Anyone? Any Guesses? Any referrals to someone who might know? These were =
found in an estate in a paper Cameradio bag on which was written =
"electro-static".=20

Any that's all the clues I've got to give you. Any help appreciated.
Thanks.
