Its the good old gold colour shade argument again
It can be a headache Elaine, but I found out that 3645 had only the old colour...
Both 3372 and 3024 had the brighter gold armour...
It interesting to find out when the different colours were used...
3645 was produced between 1993 and 1998... the old dull gold shade was used during that time, while the brighter (or shiny) was used after 2000.... so maybe there are some 3024s with a dull gold shade since the set was produced between 1999-2003, but the 3372, produced between 2002-2005, was certainly bright gold.
All klikcies have the same hair and beard in these sets, so your was certainly added by its previous owner.
Hope that helps
