Twilight Zone plastics

[Happypin]

Just done a deep clean on my T.Z and replaced 90% of the plastics, but where do these go please ?

I remember puzzling over 3 of those small ones several years ago. A bit of a mystery why they are in the set, prototypes that were never used? The cloud shaped one goes on top of the shooter lane gate. Not sure about the square one, my TZ in storage atm.

Just had a look over my TZ and cant find any of those except the clear one at end of shooter lane as per post linked to.
