I assume that by the mid-1950's everyone went to the Federal or National Stock Number

Hi Brian, my "special" reference books showing not only Neutral numbers to
Ford-GMC-Dodge numbers but also the other way: Dodge numbers to
GMC-Ford-Neutral numbers plus etc. etc. The 4 (small) books are undated !
