This is one I picked up and I don't know what brand it is. All I can make out on it is K NN also 136 or 186. It's rather heave so I'm thinking it's 136 but it's my first anvil so if anyone knows for sure what it is please let me know. Not that it matter though. It's mine for life! Yeah those are push rods from a 350 chevy lol. They were handy at the moment.
