We recently purchased a Peter Wright anvil. We did not know anything about him till we did a little research. We now know that he patented his anvils in "1850". Our anvil says "PWRIGHT" on one side and on the other side it has the stone weight of "1 0 4". Is this an earlier anvil before he received his patent? Haven't been able to find any info on our anvil. Any info will be appreciated.
