In 1956/57, Revell made several 1/48 scale vehicles. The aforementioned truck is one and included a policeman, with a scale Harley, writing the driver a ticket. These were repoped in the mid 90's and show up on eBay quite frequently. I received the scale White Tanker truck, with two attendants, only yesterday. I still have my 1957 Revell catalog but cannot say if the Buick and Ford convertible were scale or not. I wiil look at my Pontiac Club de Mer and Cadillac Fleetwood Eldorado Brougham but expect they are larger like the stupidly expensive '57 Ford Coiuntry Squire station wagon model (not reproduced). I am going to sell my FCS wagon I build back then! Of course I have to build the gas truck but it'll look nice with the gas station from Mr. Muffin's Trains.
Here's to a very Merry Christmas and a trip down memory lane to our childhood hobby shops.
