I picked up the parts to the Walthers Modern Conveyors today. I wanted to build it to use for a Ukrainian Mining Complex. It's an HO scale kit. But it looks like it will work well. I built the conveyor and the supports but have not put them together. The kit does not have the to and from buildings for the conveyor. I hope to have this finished off by the weekend and ready for photos. Here is a link to what I had bought.
The next building set I would like are some silos. I am thinking about this set or the ones from Impudent Mortal.
