Hey, Bikerray
Hoover made 4 special colors. They are known as the 'condiments": mustard, mayo, relish, and ketchup. The ketchup one is a full hood which came out in 1975.
That model you have there, I believe, is called "Canton red". It is not one of the condiments. They are referred to as "full hood models".
I have the specs and that model at home. I believe I have all 4 condiments too. I'll have to take a picture of all 4 .
