In those times (and yes I am old enough to have actually used them) we used plainer normographs or lettering guides[0] where the ink pen was used directly inside the template.

Before the advent of so-called isograph/rapidograph pens, we used those weird looking pens as depicted in the wikipedia article and you had to be very, very careful as it was very easy to inadvertedly ruin a drawing with ink coming out of the (open top) reservoir.
