Is there any info on country of origin? That might narrow it down a lot...
I think it probably is late '50s, as core seemed to get a lot more compact in
the '60s, and a single stack of 40k capacity would have probably been unusual
on earlier '50s systems.
Problem is, it looks like a lot of stacks that I've seen on machines around
that time - same materials, same white lettering etc.; as we know the capacity
then perhaps knowing which country's system it was would be enough (I'm not
sure if it's possible to guess at machine word length purely from the core
