That may be very true. Many Collectors has tried to catalogue the many variations and has fallen short of being able to complete this large under taking. Besides being able to identify the early variations the first task is to find them. With the first and second year of Harbour Lights being absorbed into the populous it is almost by chance to find one of these. Except for one new tool. EBAY!!!. With ebay we have seen collectables that we would have never seen otherwise. All we need now is to start seeing some CH-1 with numbers between 120 and 180 and maybe we can identify this mystery of the black verses green.
