Nice shots and brings back a lot of memories. My dad bought a 1948 Dodge (same car with less chrome) new, same year as I was born (no, not in the back seat), and kept it for about 10 years.
I believe it was the first new model after the war, so we used to kid that it was made with leftover tank metal. You could sit on the hood and the sheet metal wouldn't even deflect.
...in the interior shot, is the red lever to activate the low rider setup?
If you're talking about the stalk on the left side of the steering column, this was a later add-on, an electric turn-signal (blinkers)! Most cars didn't have'em in 1948 (heaters & AM radios were also options), but you could buy them later & mont them to the side of the steering wheel. Anyone remember their hand signals for turns?
