I beleive the Weyerhayser all door box car was a kit by Amity Star. About 15 years ago, I built 6 of them. I built the basic body, then covered it with .010 styrene. I then used styrene to complete the cars. Styrene shapes are much finer than the wood shapes that the kit has. This kit also came with Green Bay Western decals. I built 3 cars for Weyerhauser and 3 for Green Bay Western. The decals for the Green Bay Western were so bad that I could not use them. I had new decals made. Had to buy 25 sets. Still have many left if anyone could use a few sets.
