This isn’t a Templar but elements of the armor are similar to what a knight of the Order would have worn in the twelfth century – when the Templars were founded. Note, there is no helmet with a moveable visor – not a common feature of armor until the next century.
The one piece chain mail extending over the head is the norm. And the kite shield one normally associates with the Normans is still a standard piece of kit.
There’s no fancy helmets or suits of armor with plates of steel that are worn in the fifteenth and sixteenth century. Boots are much simpler that the footwear that will follow in the centuries ahead and the Templar used swords with minimal ornamentation.
