Cingulum - which is the most accurate version?

[M. Demetrius]

Can some Deepeeka cingulum be modified for improvement

Of course. But if you have to do much modification, it's probably better just to start with the plates and buttons and buckles, oh my, and just make it to fit you exactly. Once you remove some of those buckles and start re-riveting, you may find that the cast plates are pretty brittle. I had that task, and it's not for sure that every plate will survive the new rivets...one little angle missed and snap! off goes a corner.
