Probably just a "standard" mercury delay

what
they sound like, add a delay to a signal, usually on the order tens of
microseconds for stuff I've seen.
Some early machines used large versions as their primary storage, they
functioned somewhat like a (more) solid-state drum memory.
Exactly. So what I should have asked (what I meant to ask) is does anyone
have any data on this part to determine how long the delay is? I'm
thinking it would be neat to try to use this (or a number of these in
series) to create a delay line memory to experiment with.
