Helmet Difference
In mid-late 1997 TLG updated the common minifig crash helmet introduced in 1987 with Space.
Whilst the Design ID is known for quite some time, I couldn't find any information towards the actual difference. Stud connector and overall dimensions seem the same.
I now realized that 30124 helmets from around 1998-2005 (maybe also later ones) can't have the visor fully closed, as the older ones do (notice the small gap on the white helmet).
The visor (Design 2447) never saw a change as far as is known. I also changed the visors between these helmets and the result is the same: Old ones fully close, newer ones don't.
