Mac,
Not sure if this helps but back in the early '80s we got our 1st Vac from Specialty Equipment (Mpls). It was a 3 motor Monorail Brand. After that Specialty sold us stainless steel trusty 4 filter bag 2 motor DOYLE VACUUMS that had stainless steel domes. I would assume that Doyle still sells the filter bags or they are somewhat standard???

Sounds like to me there identical to old southern pride vacuums with the band & one big motor and the filter is very shallow and the corners get sucked up in there when dirty. Last time I bought some bags was years ago from Carolina pride my uncle still has a few in use. I got 10 old ones in the shed.
they were crap when they were new.
Yes, when you add freight, labor to remove old and install new, and sales tax, you're right there around 2K each. Apparently some don't understand this.
