Here's my modified Amplidan, I loved the Massey key that I sent with at Bob Merriam (W1NTE)'s museum in Rhode Island - New England Radio and Steam Museum, that the next best thing was to create a ball so I could flap my arms like a duck, like I did with the Massey key.  Bob Merriam said he's never heard anyone send on that key that fast, and I'm a sender who struggles to send 20 WPM in my senior years, and when I was 30 I found it difficult to send at a 25 WPM speed on a hand key - thank God for Vibroplex.  Here's that magic day I fell in love with the beautiful Massie wireless key, I grabbed it like a pump handle and then finally I grabbed it like using the wings of a bird, and I flapped it and it went very fast.

Photos - my modified Amplidan with the big ball "cupped hand piece".  The big ball itself.

Photo of a SAILOR Denmark Radio installation - notice that Denmark, Sweden and Norway used BLUE instead of green for the silence periods for 2182 kHz MAYDAY distress - Russia was the other non-standard nation they used "pink" - the rest of the world used green.
