You may want to check out the
Vintage Photo Archives to see other examples of
1977 Sovereigns.
The folding part & dimensions sound appropriately original...it should fold flat to make into a bed. However, the different fabrics may not all be original. In the older trailers, things get modified for various reasons...oh, if only they could talk!
If you could post a picture that may help, someone here that is more familiar (than me) with that particular era could help.
