First off, thanks for all the good information- it helped me have a better idea of what to look for when I went this evening.
I ended up getting the smaller anvil for $90- more of a budget issue than anything else. Turns out, it is not a harbor frieght anvil as expected, but a 60# Vulcan with an arm and hammer logo on the side.
I gave it a little test with a bit of file (I forgot to grab a hammer on the way out the door) and it has a nice *bounce* to it, and seems to be in reasonable condition with a few chips out of the sides on the top- but an almost perfect horn and nice holes.
Soon as my wife gets up, I'm going to clean it up a little and give it a trial run. But of course, as with any new purchase (especially something that is a little older,) I'm looking into it's history a little right now- anyone have any good links or information about the Vulcan anvils for me to look at?
Thanks again!
