I have just completed my digital museum of the barrel organs made
in Steinkjer in Norway between 1850 to 1910.  The barrel organs are
named Steinkjerpositives.

If you want to read about the history, and look at the instruments
and hear their music, please visit: http://www.steinkjerpositiv.com/ 

The site is in English.

The best,
