These are LGB logging disconnects with Ozark miniatures brake rigging, I believe Grant line brake wheels, and pawl rachets. The log bunks our Ozark Miniatures kits. I also added chain on the rooster polls, and although not visible in the pictures, chain was also added from the disconnect frames to the brake beams, with brass nut and washer detail. In one of the pictures you can see broken track. After 8 years I have had to replace all of the Accucraft 250 code rail as it broke like this everywhere.
