To answer your question, the Quiet De Luxe did come with a paper guide; however, based on your description it sounds like you're asking about a paper rest. The paper guide is the angled bracket that slides left and right on the paper table and helps to guide in a sheet of paper at a desired location on a platen. A paper rest on the other hand, which typically extends from the paper table, is what supports a page upright as it comes off the platen.
The body style of the Quiet De Luxe changed during the '40s, so I'm not sure which machine you're specicfically asking about. Regardless, I'm pretty sure that neither featured a paper rest, certainly not the one that appeared in the late '40s.
The paper rest has always been a pet peeve of mine and it infuriates me when a machine doesn't have one, partly because it means you need more desk space to use the machine, but also because you have to constantly lift up the typed page if you frequently need to refer back to something that you've typed..
