I wasn't responsible for the originating list so would have to check when I can, I was under the impression that cloth barding was dropping out of favour by this time? If you can point me to some evidence otherwise I would be grateful.

I am not a medieval specialist but I will ask.
Anyway, without cloth barding, you can disengage from a barded cavalry, so it is ok with me. I just see that in other lists in the same period option was there, that'all !
