I Feel Your Pain!
One of our members here sold me an absolutely beautiful Electrolux 1205 that had been the vacuum of my dreams ever since I'd coveted one in the window of our local Electrolux agency back in 1972. It was bee-yoo-tee-full.
Unfortunately, its plastic caster guard broke within weeks (helped, I suspect, by my other half's epic clumsiness). This was absolutely no fault of the seller. The caster guard is a part that is no longer available, and even if it was, it would be a booger to remove the old one and install the new. I ended up tossing the machine, minus the motor the seller had so carefully rebuilt, and a few other parts.
I have another 1205 I'm working on, but it's not the same. That first one was soooooooo gorgeous, and a dream come true.
