I've got a lot of NuTone stuff in my house from that era. It is mostly bathroom exhaust fans and heater/exhaust fan/lights. One of them is a curious contraption that looked to me, earlier, to have a way to make it into an HVAC supply, possibly in a controlled manner . Now, I have some more info. Please forgive a little hijacking the thread Thanks for posting that link to the catalog, North Texan. I love that 50s ad stuff. I've got between 3 and 5 things out of that catalog in my house. First, some residual, nonworking intercom equipment. It looks like I have a 5000 series Hood-Fan in my kitchen with its dual squirrel cage blowers. Now that I know what the original lights looked like, I can take a close look at what the electrician/owner did when he hacked a 3' T12 luminaire in there. I've also got a "Fold-away" listed right under the 5000 series. The high wall mounted fan is probably a NuTone. I'll have to take a close look. The outside hood says NuTone and I feel it in my heart that it has a "patented no flutter shutter". I have, however, only a simple snap action switch ganged with a light switch in the same box. AMS, you want to sell your switch? I might be able to use it though I might need to pull some cable. Now, the bathroom heater-fan might be a close miss. My dampered outlet is definitely at the top rather than the side. Mine also appears to do more than this and the model number is different, longer. Maybe the longer number is an indication of added functionality. On the other hand, perhaps my was modified by the owner for top outlet. The bimetal spring might be what closes the (original) louvre.

Whether you need permits depends on your city/county codes. How difficult it is to return to the original depends on how much framing was added. Start by removing the windows. The only way to find out how much framing was added is to remove the sheet rock. That should give you an idea of any framing added for sheet rock installation and/or how big the old screens were. To replace windows with screens means all the sheet rock has to be removed. Looks some was added to the old exterior. Most of the trim has to go. Not a really good DIY project unless you have some experience in demolition. To have it done may run a couple thousand dollars, and maybe that much more to refurbuish it.

"Reconnected all the black to black, white to white..." You've miswired your three way switch! PS why are you not being gracious to the folks that tried to help above?

something was added later. i'm better it was the stone veneer. I'd paint that portion of the brick black to match the columns. (yours would have the holes, obviously) If you also want to paint around the door, you can do that in black as well, but I'd change out the door color. Or, preserve the brick and cover around the door area w/a board and batten. paint it white or the black Bring in a better looking porch light I'd do a wood craftsman door if you go black on the porch area Romabio has a masonry paint you can tint to any color.
