Can't speak to the 50's but side trim on my 47 is installed as tubman describes -ends of trim are held tight to body with sliding clips that use a stamped sheet metal formed bolt. In between are the basic wire snap-spring clips. I had to remove the interior panels to access them. And I totally agree with tubman, don't try to pry the trim off. You will likely stretch and distort the thin SS trim metal beyond repair. I think I've seen both types of clips for sale on the internet.
