But what type of memory is it? Delay line, CRT tube,
Drum?? ? ? ? ? ? ? ?

Bonuspoints if the machine can be identified :)?
My guess would be CRT memory from the 701.
It looks too short to me to be mercury delay line, especially
for 4k, and it definitely doesn't look like a drum. Plus,
I don't recall IBM ever using delay line for main memory.
