Thanks!
It looks a lot like the font used by Signature plastics for their DSA keys.
Slight detour: Desn't SP uses Gorton Modified for DCS and a different font for DSA?

Over 30 years ago a font was developed, based on a modified IBM standard, using a Gorton engraving machine. Thus our standard font, Gorton Modified was born.There is no electronic file of this particular font, however Arial or Helvetica come very close.
Today we can offer 3 additional line fonts - subject to a fee.
