Nice score ! They make nice anvils I couldn't tell if it was well worn but I believe they get very hard from use
You are Right about that! I made an Anvil apearing metal object from Railroad Iron and even drilled a Pritchard hole in it.
The first 1/8" was so work hardened I almost gave up, went through several bits and lots of cutting oil. But when I goT through that it drilled like butter.
Shaping it with a 4 1/2 " grinder was a test of paitence tons of time and taught me a lot. But I would not reccomend anyone do it.
Just take a chunk and start beating on it!
