I picked up a Case Temperite with the clear lucite scales off of feeBay

Having a desire for a Case blade, (my dad had one) when I spotted it ending soon, I didnt have time to ask for more/better photos, or ask any questions, but it did look decent in the pictures it had, so I put in a last minute bid, and won it.
When it arrived, the blade was in great shape, but as it turns out the blade does not fit in the scales. Its as if the scales had shrunk in size like a wool sweater in a hot water wash.
And the first thought through my mind was "Shrinky Dinks" Those old toys that you drew on, put in the oven, and they shrank up.
Would anybody know if lucite shrinks when heated? is this a case of somebody trying to straighten out scales only to make a disasterous discovery? Or did somebody put together a blade with scales that it didnt belong on, just to make a quick sale off a sucker like myself?
If lucite DOES shrink when heated, maybe somebody should add that notation to the "how to" so nobody else makes that mistake!
Yet another one added to the "will restore this in my Copious Spare Time" pile. Oh well.
