If we assume that the values marked on the transformer are impedances as opposed to resistances, then according to my calculations ( from n=√(Zp/Zs) )
the ratios would approximately be :-
168Ω : 3.2Ω | 7.2:1
41Ω : 3.2Ω | 3.6:1
4Ω : 3.2Ω | 1.1:1
These could be checked by measurement.
So whilst I agree with Trevor that it could be a 100V (or lower) line output transformer (although they are normally quoted by power output) I think it's more likely to be some form of impedance matching type for a transistor based amplifier.
