The spidery type component showed in your picture was an integrated
circuit
that mounted into transistor-like physical. I believe the part number
is top of the cover that hide by against the board. It could be
multitransistor
in one physical appearance.
In early days of intergrated circuit chips tend mounted on transistor
type hardware
before they revised into new physical shapes as today.

Ok,
I have an old Anita 1000 calculator which I think dates from around
1967. It is all discrete components mounted on a number of seperate
boards. One board has a funny spidery type component on it and I don't
know what it is. You can see a picture here:

It's a bit difficult to see, but it looks like a ferrite torroid with
windings on it. Such things were used as pulse transformers, oscillator
coils, or logic gates.
