Hi Ian, the current transformer may well be a "ratio arm transformer". This was a device whereby the number of standard R,L,C parts could be reduced by using different ratios in the transformer.
Such bridges were normally pretty accurate.
Leakage of oil may simply be due to poor seals rather than the unit having been "cooked"
