I received a reply from Lery (Валерий Пахомов),
UA3AO, he
sent it directly to me.
Yes David,
Its name is The Modified double-lever Vibroplex Griginal. =
Двуручный
модифицированный виброплекс. The very first one was made for a
real
spy (in Russian we usually say an agent) of Soviet Intelligence
Service.
As far as I know the only one who can send with one other than
myself is, Владимир (Vlad) И. Сутулов, UA3AMY.
