I have one made by "Advance", most of the transistors are early
germanium and (I vaguely remember) some avalanche devices to give sharp
pulse edges.   They were exotic specialised equipment used mainly in the
nuclear and telecommunications industries. 

As far as I know, their main use was producing pairs of pulses close
together to check that devices like Geiger counters weren't missing
pulses due to latency.  They could also generate test waveforms for
video links.
