I have an old anvil with the capital letters DB. Do you have any info about where this anvil is from? 

Can you post a picture of it?  That might be helpful to the experts here.

Here's a thread where the DB is mentioned being stamped on a leg vise... Dalsbruk.

 

Now if you Google search Dalsbruk anvil you'll see some pictures and info posted by others.

 

Cheers.

 

 

It could be made in Dalsbruk, Finland. There was an ironworks there back in the day. I know they made nails and anvils, don't know what else. I'm posting some pictures of DB anvils. Note, one is two-horned. Dalsbruk means Valley Forge.
