Just picked up this anvil and when I got it the only thing one could see on it was "Sheffield" and then the stone weight of 1-2-17 (185 Lbs). I was told it was a MouseHole anvil but after buffing it off I found the word Fawcett above Sheffield. Did a little Pigot's research and found out there was an Anvil maker by the name of Miles John Mason Fawcett in the Sheffield area around the date of 1841. That's about all I could find out about it so if anyone has any other ideas on this maker I'd be interested.

I haven't finished cleaning it up but from the looks of it, it appears to be in pretty good shape. 

His works was situated in The Wicker, which was a centre for many forges and foundries as the River Don was used for water powering machinery. also had nearby canal and railway facilities to provide raw materials needed in steel manufacturing, 

Thanks for the info. Much appreciated John. Cheers.
