Hi Bernard, How are you. I think you may have got the answer to my question, Acording to the link you posted, the Alpha Kit I have pictured looks to be a type IIA Pre-Damon kit. this would date it from the very end of 1969, the next run of kits would of had the 3-2-1 count down header card.
this would make perfect scene as this KS-7 Kit has many pre-Damon components and was not
in production until 1970, the Start of the Damon era.

Thank You, for your in-put.
