Looking through some old threads I came across a discussion "More about Nelson Clocks "referring to the "numbers" model #2281. (I should have started there)
Attributed to Don Ervin from Nelson & Associates. Circa 1959-60, which is surprising considering the color combination, and the font really made me think it was much later into the 60's, or even 70's. Not my favourite by far, but still interesting.
I will leave this information as a semi solid lead.
Thank you design addict of yesteryear
