Hi Bako. This has suddenly become my favourite thread...
Great collection you have there, regards having all of them depends on how far down the detail variations path you want to go, but essentially there are others you might want to chase.
On my vastly outdated (1993), master listing for this model, I have these listed.
4 Turquoise-Blue versions.
9 Gold versions.
4 Red versions.
plus another Five waiting to be checked and added to the listing.
