Vacuum Cleaners Discussions

Id like to start be saying hello to every one.  I'm not sure if this is the place to ask but i was wondering if some one could help me with a type of vacuum that i have.   I have an old Eureka Model 100B that i'm trying to find bags and parts for i know it takes type D bags and id gladly buy a whole vac if any one had one but i can't seem to find any thin on this vacuum and it has no name on it any where just model number 100 then the letter B.   Any help would be wonderful.
