Great description Wayne and welcome to the board.
Guys here is another one for the playtest FAQ.
If you see “Ad Hoc” heavy gambeson or something like that under armor, it is something from the character generation software. In the system we use to make the characters, you can buy armor as a complete harness (like Gothic or Milanese Harness) or ‘Ad Hoc’ meaning different pieces and then it tries to construct a panoply out of that.
Johannes armor consists of Bronze Bracers, an aketon (textile armor) a brigandine, and a bascinet helmet.
The way the armor is listed on his sheet isn’t quite right though I will update it. There should be two tiers of protection, the light and heavy armor.
