Deciphering segmentae pattern

[MattR]

I'm trying to recreate the segmentae (and clavi too) of the late Roman tunic from Egypt shown in Figure 52 on Page 63 of Graham Sumner's "Roman Military Dress" and Page 8 of Raffaele D'Amato's "Roman Military Clothing (3) AD 400-640," but I can't quite tell what some of the motifs are, namely the large figures in the center of the segmentae (are they human figures or floral?) and the small figures inside the circles on the segmentae and clavi (some look like diamonds, ducks and old-fashioned leather footballAmerican helmets!).

Any ideas on what they are? Or does anyone have a high-resolution or close-up image of the segmentae/clavi? D'Amato's book says it's in the Berlin Museum ... has anyone seen it in person?

Thanks!
