Also, for gasmansgp, your comment about possibly being used in a commercial environment due to the '4' digit display - Which is for sure a factory faceplate and has not been hacked - The location i found the pump, there were some trucking business and also an 'aerodrome' that flies vintage planes around - The junk shop i bought it from specializes in 'local finds', so maybe it's possible it came from one of those locations once it's usefulness was exhausted -

Always fun to try to piece together history based on evidence and guesswork!!!
