Stroh violin

I was at the Greenmarket on Sunday and the Penny Jar band were playing.  It was quite warm (over 90F) and the chairs were set up on the lawn of City Hall, under the trees.  So the band were facing opposite of the usual configuration, giving me a look behind the scenes, as it were.  And I saw this!

This is a Stroh violin.  It's an amplified violin, but the amplification is... mechanical rather than electrical.  It was invented by John Matthias Augustus Stroh in 1899, before the microphone.  You can hear a pretty good example at http://www.youtube.com/watch?v=IkO5y-To3H0.  Now that we have microphones, there aren't that many Stroh violins in circulation.  I was very happy to see it.  Alas, the A string broke (normal wear and tear) and the violinist wasn't able to play the full range of notes.  But she did play it for me!  Nice.
