1950’s Evans Sonic Scout

I just picked this Evans Sonic Scout up yesterday at a local auction.With minimal research I believe it to be from the mid 1950’s.It appears to be mostly complete and original,light I am sure is not original but sort of goes with the Sonic Scout theme as it appears to be in the shape of a rocket ship.If anyone can identify this light as to a specific bike,that info. would be greatly appreciated.It is marked Delta on top.
Thanks for your time in any reply…
