Bugera Ts. cab speaker swap

I have A Bugera 4x12 Turbosound cab. I would like to know what WGS speakers should I install to give me as close to A 1960 cab sound or as good.

Vintage 1960 cab: Green Berets
Current production 1960: Vet 30

Sucks that “Turbosound” … such a GREAT old name, has been pooped on by the new Chinese owners, dosn’t it??
