Luggage racks are they for a Model A?

[1928 Sport Coupe]

These two luggage racks came with my 30 Model A Town Sedan. Are they for a Model A or some other car. I assume they were produced by an aftermarket company and not Ford. I did not measure them but I guess about 26" wide X about 12" deep. They fold down and look like they would hang on a rear mounted Spare tire. There are slots in the rack frame to accept leather straps to attach to the tire. They fold up. There also were two of the running board expandable luggage racks included. Am I thinking correctly? If anyone has any idea or information I would appreciate it.

Was there any rear mounted luggage racks that were 36 inches long X 14 inches deep for the Model A's. I have a trunk with those measurements I would like to use. There is enough space between the tail lights for it to fit.

Thanks for any information.
