recall that there exists an extension that will allow you to use the parser
in that way - but the Foundation projects do not have such an extension
installed and cannot be convinced to render a page for you that would
accurately show what ELs it might have had at a given date.
That would be the Memento [1] extension. I'm not sure this is even
theoretically possible - the parser has changed over time and old templates
might not work anymore.
Your best bet is probably to find some old dumps. (Kiwix [2] maybe? I don't
know if they preserve templates.)
