Less than US$2 a pound, not a bad price in that general area I would still go and offer a bit less in cash in person. (or get them to throw in some other tools!) Google: anvil ball bearing test That test will tell you if it has been softened in a fire; if it's still hard there is a lot of life left in that anvil! Just whatever you do don't grind, mill, sand, etc the face of it! Working hot iron will shine it up nicely. Please note this type of anvil will NOT ring when hit with a hammer---EXCELLENT as you do not need to wear hearing protectors using it or flee from neighbors with pitchforks and torches.
My browser, google chrome running on Kubuntu, if I back arrow from the forbidden page and go down the the reply area and click on it it will restore my original writing that I can then copy to somewhere safe as I have never had any luck trying to repost it until I have totally exited and then came back in and do a gripe post and edit.
Looks like a Star anvil from the last half of the 19th century most likely. Is that hole in the bottom 1 7/8" in diameter? The patent calls it a tempering cavity... The star anvil is like a Fisher in that it has a steel face and a cast iron body and is a quiet anvil. Check the face's hardness by the ball bearing test and tell us how much it weighs so we can give a judgement on if that price is high or low. (Your location would help too) Note that these anvils are discussed in Anvils in America pages 197-203 including the patent documents
I remember one quad-state when the knifemaking demo had a fellow doing a can weld and had his assistant weld shut the can---someone asked him about possible issues heating a sealed container to which he replied that his welds were never that good---and then the can welded up by his assistant popped in the forge! Me, I'm *safe* from that problem!
They are the reason there is a pair of sandles by each side of our bed; running into one in the middle of the night is not restful and the animals will spread them around the house when you are not looking. Every door to our house has a piece of catwalk grating to scrub your shoes on before entering.
Usual is Ball hitches of various sizes with ring and pintle for very heavy load systems, + gooseneck 5th wheel systems. Typical failures? I'd say tires. Ball hitches do fail from the balls becoming unscrewed or perhaps more often lift off from improperly balance loads. Safety chains are a cheap and easy method of back up for one of the critical failure points with several failure modes. You only have to need them once for that "hassle" to become a welcome part of hitching up!
