Heddon "Instruction & Parts Folder"

[Dive4Blood]

I have come across an asbolutely mint, pristine[b] Heddon Instruction and Parts Folder[/b] but i dont know what year. Part # 38567. There is a crease in the front page but no tears, rips, smudges anywhere. Still folded beautifully. Besides exploded views and numbers of all parts of models current to that year, this "manual" has some tips and instructions as well as a list of Heddon Service centers. I don't know the year. If seriously interested I will carefully unfold and read off some model numbers and maybe you can tell me what year it is! Paper is yellowed and obviously aged but not too brittle to handle.
