These are a simple 3 piece award, with a single larger 17.5cm award and 3 smaller 12.5cm awards.
The panels are bolted together using a chrome sleeve with some 1/4" threaded rod between the plates.
The clear mid panel is designed to 'float' on the two spacers for a mildly interactive effect.
The front panel carries the individual titles and attributions.
Spare space on the clear and rear panels are also used to produce some commemorative key-rings designed to accompany the awards.
