Here are some posters from a Burnside dealer presenting the new '53 Burnside Special Deluxe in four different colors. The Special Deluxe has the new 3-speed Super-Matic automatic gearbox made by Burnside and a air suspension which gives this car a smooth ride.
the posters look really nice like but they don't really look like the burnside, they seem too low and they don't have the things on the hood. the information in the OP also isn't accurate, it has rear leaf spings(I'm not sure about the front, probably not air though) not air suspension like I was hoping for. I'm not sure but I think that might be a glass roof, more likely its just a white roof but a glass roof probably wouldn't be too out of the question considering its from the 50's and the safety requirements were a lot looser so manufacturers could actually do cool things like that and it wouldn't be out of place in some 50's scifi movie or something.
