I have a strange problem with a type of model, and I need to hear what's going on, especially for you Ebay warriors who search for old kits. Some time ago, I acquired 3 old Revell snap kits in 1/32nd. I was going to add details and nice paint to make a few additions to my Pioneer chassis stable (some long time ago, I got a bargain on 10 bare chassis, and I have been doing great things with them ever since), and since they are easily adjustable for wheelbase, it has gone well.
Now to my problem. These kits are old, and the box art is yellowed with age. I have found that these kits (2 early T-Birds and a '56 Corvette), while seemingly fine, don't fit together. The unchromed parts seem to have shrunk until the chrome parts no longer fit properly into the body shell. The molding is sloppy, as you would expect from a toy-like model meant for kids who have no idea what the car is supposed to look like, but this is really profound. You expect Lindberg, Palmer, and other junky stuff to be wildly out of scale, badly fitted, etc, but this is bad enough to require cutting the snaptabs off to get an attachment at all.
Obviously, I can overcome this, but if age shrinks plastic models, I need to know that for a fact. Thanks.
