Dux : A basic overview of expansion to USA.  

That 1966 catalog is as good as I've seen for Dux, except possibly the early one posted on Mats Linder's site. I wish my digital copy was higher quality.

Thank you very much, you've made my day. I've been searching for more than two years for anything related to this. 

Judging from the fit and finish of the feet (more like skids, really), I think they're original. It's interesting to see the different back cushion design, too. The added feet and lower cushions make it look lower and sleeker. 

This may be a good jumping-off point to find more information/images, so I am very grateful!

@dustdevil. My plan is to start with the information on Mats page, as it is the earliest catalogue I have seen, and work forward from there comparing those models, with images of the later models from your catalogue ( if that is OK with you ?) and vintage adverts that I have found  on the web . 

Thanking you again for that catalogue . I have enjoyed going through it .

Maybe  I will just use the images from you to answer ID or general information questions , as they arise, on the Forum.

I used the model number for the 6352 Sofa to find an annual periodical on Google Books called Furniture Forum. The 1966 edition had a mention of that model, so I'm going to get a copy from a university library and see what other information it has. Academic libraries and archives can be a great source  for obscure information, and Google Books is a great way to get leads. I'll share any valuable information I find.

@midcenturyslattern. All information gratefully received.

Cannot remember when I was last in a library!

My inter-library loan came in, so I now have a copy of Furniture Forum, Volume 17 (1966). I took photos of the four pages on Dux Incorporated, which has the Newport News, Virginia address, and shows a black and white copy of the color photo from earlier in this thread, with the couch that resembles mine.

Here's a link to a photo gallery with the four pages. I can make proper scans later.

@midcenturyslattern. Thank you for that.
