The advice you got from Taffeta and Hathorcat sounds really good, and your best option IMO.
I don’t know anything about G2s but I did a quick search on local Scandinavian BST sites, and found the following G2s in lots that doesn’t come from collectors(making it more likely, if not for certain, that the ponies were actually sold in Scandinavia).
- Magic motion Ivy (looks like the first edition of her)
- Morning Glory and Baby Dew
-Baby Swirly
- Princess Crystal
- Prince Clever Clover
- Royal Masquerade Sky Skimmer
- Bright green one w/color palette as symbol (couldn’t find her name)
- one bright pink and one orange baby pony (couldn’t find their names)
There were many others as well, but I didn’t have time to check them all
However, I hope this give you an indication of what sets were sold in Scandinavia. Good luck!
