No problem.
the HLMD is the "Hessisches Landesmuseum Darmstadt".
There, actually, are shown the finds of Glauberg.

no. 14 is the fibula.
Why trouser: the celts worn bracae. At the statue were fragmenst of paintings found. maybe an trouser. A lot of finds show trousers in the lta (look @ dürrnberg or hallstatt)
Why longs sleeves? because it was terrible cold and wet that day!
And why not? we are celts no greecs or etruscians.
There are no pictures of "batwings". It is forbidden to make some and also impossible because of the very bad light in the exhibition.
If you have any more questions go on!
Greetz,
