Proposed Centurion Pteryges

[caiusbeerquitius]

However, both the Adamklissi and T's Column show regular rank and file legionarys and auxilliarys in pteryges (looks like single row as well). Can you imagine the cost of equipping serveral thousand soldiers at least in high cost linen pteryges?

Magnus, this is nothing compared to the cost of equipping several thousand soldiers with metal armour. And linen was not that expensive. Wer´e not talking about super-quality super fine linen here.
Your pic: as far as the upper / shorter row of rectangular pterges is concerned: there is something below it, namely the lower / longer row of rectangular pterges. For the lower row itself: could be or couldn´t be that they were next to each other / overlapping. Also, if you look carefully you will see that the longer ones are right in the middle between the shorter ones, which gives a nice double-layer at least for the upper row. If I were wearing this, i would be much happer with it, than with one without double layer, especially in that region of my body.
