Sheilds - Adjusting the Sizes - Scale

[dimitrios the samian]

Hello .....

I have noticed that shields are always larger than the actual soldier on the bif plate .... sometimes almost twice !
They seem to vary , So they must be adjustable somewhere.
Scaled down somewhere .
Can some one point me in the right direction please .

Below are two pics of very large shields ..... ( Neg Infantry especially )
& also 2 bif plates were the shields are more true to scale , side by side in perspective to the soldier .
