The Harbour Lights Collectors Guide, published in 2006 listed the counts of production on pages 41-43.

376 unique items (not counting various versions of Cape Hatteras, for example.)

Through the end of 2006, Rod Watson calculated a 'complete collection' would have included 723 versions of 376 lighthouses, lightships, Fresnel lenses, life saving stations, Coast Guard boats and other items.

HL didn't release the production counts on all the pieces they made (i.e. GLOWs). We only knew the counts on 391 out of 723 pieces (through the end of 2006). Tallying up the total for those 391 pieces, it came to 2,192,668 replicas with a retail value of $141.6 million (assuming they all sold for retail.)

Is there a link to a current list of All the HLs made through the end of 2011?
