Michael, you certainly got the 1973 gasoline price range pretty close, although I don't think it quite got to 75 cents in '73, while I still lived in Boston. Darned close, though! And I sure remember the gas lines. But I had a '67 VW Beetle at the time and it only held 10 gallons of gas.
The people who had the foresight to buy out dealer parts stocks are now reaping their rewards. When I attend the Auburn Automobile Auction, formerly Kruse's, there are some dealers with amazing stock that obviously comes from mass buyouts. I just love rummaging through that stuff.
Regarding the kitchen cabinet handles on your combination medicine cabinet, it's no secret that Eureka, and most likely other coacbuilders too, often bought parts from local stores or supply houses, to keep the money local and be able to see the actual item before it arrived on some delivery truck. I know that to be the case with the interior sconces that Eureka used. But of course, try to find an identical one now!
