Short story - Coleman Tent Trailer was bought out by Fleetwood Folding Tent Trailer (thus Coleman by Fleetwood) - that since went bankrupt and a lot of IP assets now owned by new Somerset Tent Trailer (did not purchase historical parts and will not warranty existing Fleetwood trailer).
Americana 'series' Brandywine 'model' - Cause in Canada they were branded Iroquois (or that is what mine said on the side of it - but is 100% correct to be Brandywine)
Coleman 1992 Americana Series Included Williamsburg, Shenadoah, Brandywine, Grandview and Sequoia Models
They also had a Pioneer Series as well
My Brandywine (which I JUST purchased new canvas for-still in shipping) is a bit older thus not sure of compatibly for your 1992 - but MANY models shared the SAME canvas and many parts to - normally covering several years.
Best to find a Sales Brochure that show the models and various specifics. Chances are the BODY and canvas is used on many models and a few years too - the interior finishes are where the biggest differences are. Check the FLOOR dimensions of the various models and the body styles - If the body panels are very similar and floor area the same - you may chance they are compatible.
To find out if they match. measure the top edge of the body where the bottom of the canvas goes. From front to door, Door Width, door to back (sum give the opposite length), Canvas width, crank top to full high and measure the canvas height and then the total projection of BOTH slide outs. Do the SAME measurement on the donor trailer. if within a year or two and dimensional are the same - you might have a match. Try to get as much hardware off the donor as you can (plastic/metal clips, domes, screws, brackets, curtains, valances etc.)
If canvas have a tear or seam/treads are giving way - you can do many repairs with a HOME sewing machine! (Older machine are better). You can replace the Windows/screen as well.
I re-sewed up about 50% of my seams and zippers that was falling apart last year when I got it, with polyester upholstery thread (they used cotton which after 30 years disintegrated). This year felt comfortable in spending the $$. After all my original canvas was 32 years old and looking to replace windows and screens (which some yahoo past owner used both fishing line and HOT melt or some kind of glue to make patches/fixes.)
If you need to get new - a good person to deal with is Chris Gungor at Camper & Recreation, Inc. http://canvasreplacements.com/
- which is where mine replacement was made! Quick to answer - gave great information. Can customize color too (but not really listed on there site)
