I have looked into that, but here is the problem. I read somewhere that the Harness doesn't fit and has bulky armor pieces namely the breastplate arms and cuisses. That is why I am looking at Anshelm, they have the pieces that I would need to create the Kit.
If the Anshelm Kit doesn't work, then I would ask Allan if he can make the pieces with the Brass Trimmings. Don't worry Sir Wolf, I have a plan, it just needs time.
If both vendors don't work, then I will go for the Kit you suggested Sir Wolf (gambeson recommendation included).
And I really need to find an answer/solution to this dilemma and be a Jolly, Happy Knight!
