The secret-squirrel brit lab alleges that they'll sell their stuff off - I've never seen a single proof that any of it has ever actually happened- beyond the cost they say that timeline is unknown.
BT in AUS simply won't sell you whatever they cooked up most recently, and they are straightforward about it too.
FES - ayup, simply doesn't exist.
If the rules aren't respected, why bother?
Similarly, when the Brit pursuit men showing up with frontal "trip-wire" style skinsuits and very long booties a couple years ago- it was explicitly banned, the commisaires were standing right next to them- it isn't like they were hiding it, they went fast, broke records, and what do you know?! No one ever said anything to them about it.
