i will tell you brandon original coffee can hoover bags are EXTREMELY rare and hard to find. i need an original 825 bag myself. when these end up on fleabay, the bags will sell for as much as a complete machine would.
it took me 4 years just to find the correct headlight lens for my 1076 convertible. i susupect it will take me that long if not longer to find a good condition original 825 bag. unless i pilfer thru another vac shop estate auction.
anyways, i can add those to stuff i look out for, but i wouldnt excpect them anytime soon realistically. when it comes to pre war machines as i discovered with my scott fezter, information is scare... parts seem to be even harder to find than info unless you dig in OLD vac shop back rooms/ basements.
btw, welcome to the dark erm, hoover side ^_^
