Very sad to hear this. Here are a few photos of the Alnavco anniversary in 2005. Rudi and Egbert Kraus, Navis/Neptun, and I went to the party at the Nauticus museum in Norfolk to the celebration. Included are also the grand exhibits of Alnavco models by Mike Meyer and the late Dave Shadell at the 2006 SMSC meeting at Fort Schuyler, NY State Maritime College, and the 2010 meeting in Boston.
