Hammond M3 Preamp Trannies: Any Uses?

[schmidlin]

Came into a Hammond chassis and noticed some preamp transformers that may be of interest:

Specifically T4, T5, & T6 (loc: center/slight left).  Are these usefull for any audio apps?
Safe to assume these are all high impedance in and out?  Possibly as an interstage transformer?

Thanks in advance.

T4 is a step-up input xfmr; maybe could be used as mic input.
T5 and T6 are used in a Vari-Mu VCA for percussion generation. Maybe could be used for a Vari-Mu comp?
Anyway, these xfmr's may not have very good HF characteristics and THD figures.
