When Roundhouse was bought by Horizon, they sold off all of the old stock because the company was located in Nevada and they didn't want to move everything to California to combine the inventory with Athearn. Therefore Horizon has no old stock of Roundhouse products. I met a guy in Carson City a couple of years ago who had bought the Roundhouse stock from Horizon, but at the time he had it stored in a large storage facility. Some of the kits needed to be boxed, and the rest were just random and needed to be sorted and organized before he could tell what he had or how to sell them. I don't know if he has them ready to sell yet or not, and I can't remember his contact info.
