Old Signs - UTOCO, American Farm Bureau, Anchor Fence, Cyclone Fence

I saw an old friend of mine today and he gave me a whole bunch of beautiful old signs he's collected over the years. He has a lot of really great ones. He has worked in resource protection for the State Parks Dept. for many years - hence the next set of signs i'm going to post. The Utoco and Cyclone Fence signs are both porcelain enamel and the other ones are not. Can the UTOCO one be restored? I think Utoco was a division of Texaco in Utah, but i'm not sure.
