Most of these I've seen have a box top.
Kenny,
The model that you have showed us came actually two ways from the factory. At the VERY tail end of production, they were packaged with the bag style that you see below in the pic I have provided. I have it on VERY good word from former dealer(s) that Eureka discontinued the boxtop bags totally by the middle of 1980. They did manufacture replacements for awhile, but not very long. The substitute bag, was like the Self-Propelled model bag with the plastic topper, but still vinyl. giving the feeling of deluxe, without the problems faced with the box-top variety.
Eureka learned a very valuable lesson, that not only were these bags MUCH more expensive to produce, they were also much more fragile for whatever reason than their standard dowel-rod style bags. The seams were not as tight and strong as the simpler bags, and the zippers seemed to be problematic. that was on MOST Eurkeas of the time tho. as we see many replacements on survivors today.
So they were done. The bag seen in these NIB sealed machines sold on the Bay, prove out said point. I take former dealer information very seriously, as they were there. I have it on word, AND have seen in person also, that while the box-tops were in production, they would ALSO put the "box-top style" on "specials" that weren't TOL. These were made up for the vacuum dealers as promos just as Hoover did and others.
That said.
Hopefully you picked this up. They are more and more uncommon as time ticks forward. If it runs it's a keeper IMHO. Also, brandy-wine color replacement bags, non-box-top were offered far longer than the Box-top style replacements were. Someone, and I forget who had a few of them laying around. This one on it, was a common bag from machines from about 1984. You could also get these later too as replacements. As a triple-filter they do marginally better than a vinyl bag, but that again is just opinion.
