I just acquired a 150 lbs Trenton with the serial number A77815. Can someone help date it for me? I just ordered A1A book but that will take a week to ship to SC. 

Thanks, Chad

Welcome to IFI Chad. Someone with a copy of AIA will undoubtedly chime in with a date.  In the meantime I suggest reading this thread .https://www.iforgeiron.com/topic/53873-read-this-first/

No one will remember you are in SC after leaving this thread.

1908. 

Thank you very much.

No sweat. 

Nice anvil!
