You're Very Welcome Micheal!!!
That is a very pretty Hoover! I have one just like it, it was a childhood vacuum for me. My parents bought it in 1987 or 1988 right after they got married. It was always the main upstairs vacuum, and there was an orange Hoover Commercial Decade 80 for the main floor and a first generation Hoover Dial-A-Matic (cream colour w/ turquoise front & no height adjustment) for the basement. My family has always been Hoover family for as long as I can remember. The blue Convertible is called the "Ranger" style. It came around sometime in the 1970s I think. It's one of my VERY favourite Hoovers!
Speaking of Sanitaire though, I have 3: the Blue-line, the classic chrome & red commercial upright w/ shakeout bag, a brand new Sanitaire Quiet-Kleen Commercial upright w/ a hose & and some of the best hose suction I've ever seen before! The dome-style hood I installed on the Blue-Line is my favourite Eureka/Sanitaire hood ever too. It's very rare to find it in chrome too, this is the only one I've seen and several others said the same. I got the hood off a Eureka F&G upright (w/ a blue paisley bag, white handle, & a shattered fan chamber haha) that I bought from our fellow member "Rugsucker" on eBay. I of course knew the condition and bought it anyhow because I just wanted that chrome hood. It gave a semi-modern 1980s Sanitaire a very vintage feel, but a very powerful deep cleaner!
You appear to have a very impressive collection yourself too!

The blue Elite in your profile pic all the way to the left w/ the original style hood & stripe on the bag is one of my favourite Elites ever too! I have a Hunter Green Hoover Soft&Light w/ onboard tools from the late 1990s, that ones at our Shore house. Then I have a dark purple BOL Elite (needs a motor & is in pieces atm) and I have a Hoover Legacy from the mid or late 1980s w/ a mauve hood & grey diagonal striped bag. I love the Legacy and I've been told by several on here that it was a pretty rare machine because it's the Legacy which was the TOL Elite, but it doesn't have onboard tools, it just has the hose hookup (I have the tools too). It's a very decent light weight cleaner too!
