I recently found this site that has more information on the four organs in this set. It includes nice details about each instrument. Very knowledgeable to be a stamp colelctors' site primarily!

This is the last in a set of four stamps issued in 2007. Promoting tourism, this is the second set of stamps Luxembourg has issued featuring church organs. The "Friends of the Organ" association has a helpful site that includes details about many instruments in the country. The present instrument is in the church of St. Joseph in Esch-sur-Alzette. Here is the page for this instrument built in 1977 by G. Westenfelder.
