Anvil hold down

I have an anvil with only U S A stamped on one side.  Can any one tell me who manufacture this anvil?

Hello Alfred! And welcome to the forum,

you kinda picked an odd spot to post your question, you might want to read the (read this first) thread, it will help answer some questions and help you learn your way around ifi, 

do you have photos of your anvil? 

 

A lot of pics. Are they of your work?
