Looks like it's cleaned up well though, can't say I like the colour myself, but that's just me, I may not like Hoovers, but I do like the Juniors... 
Yeah, Hoover didn't get the memo that dirt goes into the bag, not the motor, when making these, all the Juniors I've had came with dirt around and inside the motor like that. That said, I hope you opened up the motor itself to clean out the packed fluff, you wouldn't want it overheating and topping itself... :S
I found that up & over guttering they used for a filltube to be rather a nuisance when I had the Junior U1104, as it takes up 2/3rds of the cloth bag's space, leaving little room for the paper bags to work, I know it was an attempt at making changing bags less messy, but, it just seemed too "clunky" for me... :\
And it's funny, the only Junior I haven't replaced the power cable on is the oldest I have, the 1334, with it's not-original rubber cable with the old-style Red & Black wires, before Brown & Blue were standard, it's in perfect shape, no bad bits anywhere, so, I left it on...
