I have a "Trenton" anvil from the late 1860's. It was the primary anvil in the forge for the old Paia Sugar plant on Maui, Hawaii. I acquired it 12 years ago when the plant shut down. It has the Trenton "brand" on it but the numbers are no longer legible. It has been represented to me as being #750. I have no idea how accurate that is. It measures 5"x22" on the flat, 5"x3.5" on the step and 14" on the horn. Any feed back on weight or? would be appriciated.
