Hello, I have some info I can pass along regarding the Ross Hoss. I am going to pick one up next week. It was built by RH Ross in texas. A friend of mine invested in the company and has the original contract and stock certificate, All the stuff is dated 1963. He didn't think mant were built as he never got his $2000 investment back. I will know more when I start working on it back here at the shop. The one I will have is all original but has been outside for years in a shed, Are you planniing on restoring yours??
