The car is O scale 2 rail and rolls on sprung 6 wheel Pullman type 2010 trucks. They were originally made by Grace Line in the 1940s and are still made by Keil Line.
The platform awning was made from plain, dark blue dress material cut with pinking shears for the lower edge. All cut edges were treated with a fabric edge stabilizer to keep them from fraying. Found in fabric shops it's something like Krazy Glue but dries perfectly clear, leaving no stain or shine on the fabric.
On a prototype awning, there would be metal tubing supporting the lower edge of the canvas awning from behind, just above the zig-zag cut. Prototype awnings could be raised (the outer end only, raised up to the roof) or lowered slightly. This one is shown lowered. That fancy cut was also purposeful. It enabled water from rain to drain off more completely from the awning and hasten drying.
