This past weekend I picked up an MTH 20-98914 U.S. Army flatcar with M4 Sherman tank load. My dealer was kind enough to break up a six-car set of the things. I did not want the full set because all the tanks have the same large number displayed on their turrets and that didn't appeal to me (earlier Sherman loads from MTH bore a large star in place of a number, and in my Army days I don't recall seeing large numbers on the sides of battle tanks).
Anyhow, I'm not too keen on the smallish-looking Sherman residing by its lonesome on this scale-size (Premier line) flatcar, and would like to replace the Sherman with a significantly larger tank (I have several beautifully weathered candidates available).
Question is this: I assume the chock blocks on the flatcar are glued to the deck. They will be need to be removed and repositioned. Has anyone here ever taken the things off and, if so, is it easy enough to do so without doing extensive damage to the flatcar deck?
They snap off if you try to pry the chock off. I put a utility knife under the edge. No damage to the decking but the two holes with embedded posts are there. Then you can move the chock and glue it in a new position.
