I can not imagine IBM making a tube version of the 7070, with no
history on it. That project would have been something as big as the
AN/FSQ-7. The 7070 was a pretty good sized machine.

So now you have a bunch of us wondering what machine you used. I still
doubt it was a 7070 if it had tubes. I bet it was a 700 series machine
of some sort. It could have been a 707 - IBM often gave oddball type
numbers out to semicustom or custom (AKA RPQ) machines. Have you
glanced at the IBM history pages? They have a gallery of most of their
major machines - perhaps you can spot it.
