Clark Propst asked: "I just finished decaling an Athearn hopper I modified to look more like a CB&Q car, as per Jerry Hamsmith’s decals instructions. I cobbled together a couple of leftover resin bits to represent the hopper door latches, once in operation they won’t be noticed anyway. Which made me want to ask: “What’s in our wallet?” No, no, no...Does anyone sell detail parts for these latches? I know there’s more that one brand?"
Westerfield #1171 for Wine door locks; none that I know of (separately) for Enterprise, but you can rob components from Accurail or Tichy USRA twin hopper kits.
