Greaves and Vambraces in the rank and file

[Tim Edwards]

To me the problem with the surviving greaves is not who owned them, but when

Most that I know are of a later era, and may not be of a pattern relevant for the late first/early second century.

One valuable clue I can give you - a suspected greave lining was excavated at Vindonissa (my favourite site!!!) which could give you a valuable clue as to the shape and dimensions of first century examples.

If you can beg, borrow or steal it, read:

Gansser-Burckhardt, Das Leder und seine Verarbeitung im römischen Legionslager Vindonissa, Basel 1942

Though it aint easy to get hold of, good luck!
