Does anyone know if each company's bag jacket (outer bag) sizes for their post-WWII classic uprights were the same as the above prior to the 1980s?
I do know that the Eureka 1401 had a slimmer bag jacket that was likely used for the models 258 & 238 but have yet to find the size (possibly 450 cu. in.).
I suspect that the older Convertibles and their predecessors would have used 8-qt. bag jackets to stay competitive.
Comes to the Rescue!
