Hi knowledgeable pony people!

I k ow this isn’t truly ‘nirvana’ but I’m not sure where else to post it...

I hope you can help me with categorizing some of my pony variants.
Most were found whilst thrifting in France (my parents lived there for several years) and the rest I got as a child growing up in SOuth Africa.

My question is this:
I always kinda assumed all ponies with a SS version but with no flocking and non glittery symbols were from a NSS set released in the UK. I assumed this set was the same as the SS US set but just with no flocking. This would explain all those ponies with non glittery non metallic darker symbols. But whilst doing some googling I came accross Strawberry reef and see only very few ‘NSS’ on there under UK ponies.
Was there ever an official NSS set released and sold? If so what was it called? And who was in The set? Or was it just variations sold in various sets?

Because many of these ponies were found in France I am guessing they could be euro releases or UK releases purchased whilst people visited UK or other countries in Europe on holiday?

The ones I have from my childhood (bought in SA) are:
magenta tulips Posey
Cupcake
Truly
Shady.
But I understand cupcake truly and shady were sold in SA and Scandinavia in an entirely unique set along with Hopscotch so that could explain them.
(Cupcake confuses me though as Strawberry Reef puts her as a UK NSS but My Little Pony Scrapbook claims Cupcake was never ever sold in UK in any form...)

I also have (from thrifting in France):
Wind whistler
Gusty (Blue painted leaves)
North Star
Cherries jubilee (darker symbol)
Buttons
Which  I assumed were all NSS from one big set.
Am I wrong?

Any assistance would be most welcome... I am really wanting to get these ponies correctly classified.

Many thanks!!
