Diameter for a tricorn brim?

[BESPJL]

Hello,

Can anybody tell what should be the diameter of the brim of a tricorn, for a Hornet head?

Thanks,

Here are measurements for a Revolutionary War tricorn taken from Uniforms of the Continental Army By Philip Katcher. You can use the KITSPY scaler to get the measurements for this hat in 1/35.~Gary
