MaKu screens on the field

Hello people,

I am building a few camps for a wargame and I wish to build a camp
for Takeda and one for Uesugi. The dimensions are 80mm by 80mm in
15mm scale. I found a good diagram in a Bryant book that shows the
camp organized, however my question is how would the Maku screens be
organized? Are they in a rectangle shap but with three sides of walls
with an open front or fully enclosed , if so where is the door
opening? Would it be a full square with a small opening in the front?

What mon would be used on the screen? The Takeda black lozenge on a
red background like in his battle standard?

What about Uesugi his love bird mon? Would his personal retainers
have that as their mon on the sashimono?

And who would be inside the maku screen? The gen, his nobori and uma-
jirushi,his consultants, some personal guard retainers. Would the
Taiko drums be inside or outside? What about the Conch trumpets would
they be in or out?

His personal horse would be the rear I would assume?
