Original case.

 

Pins.

Hot enamel.

Polished reverse.

 

Color variation of the case.
"Dark navy".

 

Obviously the authors of this book

had no idea about existence of early better-quality specimens.



But then again they were also totally unaware of the special meritorious member badge https://asiamedals.info/threads/special-meritorious-member-badge.23253/
And even regular (!) member badge was unknown to them https://asiamedals.info/threads/regular-member-badge.23258/

 

Late "light" badges.



Aluminium alloy instead of heavy metal (only pin is still in low quality metal) and paint instead of hot enamel.

 

Sometimes the color of the white paint gives off yellowness.

 

"Dark navy" (almost "dark grey") variation of the case.



Badge.

 

This statement from Murphy and Ackley book is also not true.

Here comes a late badge in wooden lacquered case.
