Questions about units and timeframe

[Teleklos Archelaou]

It's not a question of whether they existed or not - just how much they were used. It's difficult to say whether using them is either historically accurate or not. These decisions may come easily to some people, but they often could be either way really.

Well, I know that such units are not included in EB, but as I found mentions (quetionable reliability aside) of them I was just hoping to find help to cast aside the doubts...
