lux cylinders
Cheers for that my friend, I have a feeling they were a bit cheeper pehaps than the z30, 55 62 "loaf" series, however my Nan used hers from 1951 right up to 1978 my Dad used to service it for her but when its motor burned out she skipped it tools and all, to my horror! and replaced it with the cheap version of the 345 thingy! Still sticking with electrolux mind because of the performance of the one like yours
take care
