What happened with Proto 2000? I've been looking up and down to find some PS2CD/4750 Cubic Foot Rib Sided 3-Bay Covered Hopper kit's and I can't find any. Not even at Walthers.com I remember seeing a lot of them at shows and even special built a couple of them for one of our club member's/seller's. I am thinking about using a handful of them for the Walthers ADM grain elivator. Just something I am thinking of putting into my layout design. If nothing else I really do enjoy building these car's more than any other P2k car.
