I bought this from ChicagoMike a few months ago and have been on and off working on it since. What's weird about it is that it does not have a model number/letter, just a serial. Looks similar to the Model D, but has a less streamlined head, and of course, no model number/letter. I retreaded all 3 wheels, including the wooden rear caster, so I can keep it on the hardwood without worry of scratching it. I added a new cord and a better fitting "Apex" bag(the original was to an Energex, way too long for this machine). The switch could benefit from contact cleaner but otherwise it is such a good vac! I have used it many times to clean the hard floors downstairs, and it does better than most modern ones! Now it just needs a better polish, and a rebristling of the gear driven brush.The last pic is the before, sans the bag. Does anyone have info on it, or have a similar one so I can see what the original bag looked like? Thanks!
