Martin,
i will take images and stay in touch. I am not sure I am paper worthy, but will work with you to take a stab at it. The stock pens are built ( banta kit), I purchased Yoders bx-3 pilot model for my hide car. It's painted and decaled. The MKT tankage car is also ready. The main part left is the building and the animals. I have sheep coming from aspen models. I already painted my chickens for the overland palace poultry car! I am conflicted on the cattle as the o scale versions I got seem 1:43-- may get some in s instead and carve the others into butchered carcasses.
