Spotted this today on a steam railway in England. Red Bullers can easily sell for $150 and double groove variants like this command even higher prices. This one, however, is a standard brown saltglaze piece which is worth about as much as a Hemi42 in aqua.

These poles have been installed as decoration and as the genuine article is hard to get hold of, its a lot cheaper and easier to paint your own. So beware and make sure if you're buying a red it is real.
