Got a Vibrokeyer from a friend with the thumb piece broken and full of dust. Left it in the workshop for a while then decided to refurbish this little gem.
It has got a little red dot on top so it seems to be the „Deluxe“ version.
Ser. No. 387446, built in 1979.
When searching for replacement of the broken part I discovered that Fred, HB9JCP, sells original parts for European hams. His website is www.morsegarage.com
First I took the key apart, cleaned it carefully, put everything together and adjusted it according the manual – a nice little project for a Wednesday evening :o)
