Finishing up some Chariot, and older Essex, and a Viking Forge Han Chariots.
These all come with umbrellas to be mounted in the middle of the body.
However in looking at some pictures of museum displays of Han chariots I see the umbrellas mounted at the front of the chariot attached to the front of the body. On the other hand I see some illustrations of Chinese drawings with the umbrellas mounted at the rear of the body.
From photos of the display at the First Emperor's tomb it appears that the Ch'in mounted them on the side of the body.
Personally I think that mounting the umbrellas at the front where they can be tacked to the wall to be a sturdier method, but thought I'd see what others might have found in researching the topic as to what is most historically correct.
