The earliest catalog I have seen that has the 'B' transformer in it is 1923, so it may be of even earlier vintage than that.
No instruction sheet available, but the hookup is pretty self-explanatory.
Following the top line on the right side of the transformer terminal guide, hook your track lockon to terminals C and X of the transformer. Now with the top selector lever on position 1, the transformer output will be 8 volts,
on position 2, the transformer output will be 9 volts,
on position 3, the transformer output will be 10 volts,
on position 4, the transformer output will be 11 volts,
on position 5, the transformer output will be 12 volts.
Following the next line with wires hooked to terminals B and X will give you 14-18 volts with the selector lever, and 21-25 volts with terminals A and X connected to the lockon.
With wires connected to terminals A and B, there will be a fixed voltage of 7 volts, between B and C there will be 6 volts, and between A and C there will be 13 volts, irregardless of the position of the top selector lever.
There is no internal circuit breaker in the transformer, so an external breaker or fuse of 3 amps should be hooked in series with one lead from the transformer to the track.
