As I wrote in the TBF forum, Ray it has some artistic license, and yep it has some correction issues. My most inquisitive guess is a sleevless gambeson, why?, surely so that the sculptor shows mail undear the tear instead of quilted material, which per see is nothing atractive. Regarding the heather shield it started being used from 12/13 century and till date everything is speculative when and how the transition from a black fra cappa changed to black surcoat and then into a red surcoat. OK there is a date guideline but let us face it, keeping in mind that logistics and communication at that period were much slower then nowadays I would still pretend that in the early periods there was a mix of everything. This is the same quible of when and how the eight pointed cross developed, nothing is certain from the existing research till date.
On the other hand artists can still have that cliche of artistic license on such matters. Why a pot helmet aka similar to the 90mm released in Girona, che ne so? Yes it is a bit stereo type but a decent 75mm and potential for a good miles christi.
On the other hand I am awaiting some goudy renditions on the major expos tables ... will see who shall be that brave to dress him up in a red cappa
that shall be the most mortal sin!
