I remember wandering through junk yards just like this. Now, we have maybe three left with a 30 minute drive where there used to be a couple dozen. Scrap prices finally overcame spare parts prices (and/or the local EPA shut them down). The last junk yard near Beaufort, SC, in St. Helena, had just as many cars this old and many more from more recent years. The owner cashed out by bringing in two car crushers and crushing/hauling over 2,000 cars out of there in two weeks. Sad, sad time for may local car guys.
The NE yard I got all of my drive train parts from for my '46 Ford Coupe looked just like this - Lots of cars left from the 30's - 50's and you had to remove anything you wanted by yourself (or with friends).
