Have anvil that has been in family for 100 plus years. My great great grandfather was a blacksmith by trade in Ireland. We don't know if anvil came across the pond to Canada or was purchased in Ontario. Anvil weighs 102 lbs (0 3 18). Only symbol is like an upside down V. I thought it was a William F.
I would like to identify and possibly date. Attached is pictures of both my anvils.
