You found this one in a junk pile and on Ebay they are selling piles of junk,
"Antique 60lb Anvil, #6, 'city anvil' cast base, no maker's mark" Starting bid is $150.00+ $53.00 shipping. I got to wonder how much work it would take to make this old guy workable again. Needless to say I have no plans on buying this anvil, it has seen some work, I wonder how many hours.
