If you know what it is, let us know. PLEASE - no guessing, I've done that below.

Its not a handworking anvil. I'm not sure what it is but I can tell you SOME things about it. -guru

1) Its modern industrial, flame cut from plate with a little machining.

2) The overhang is to get into a tube or under the flange of a channel shape.

3) Its very likely an adaptor for a press brake or similar machine but could be more specialized.

4) The hole at the end indicates it MAY be for punching or riveting, possibly alignment.

5) BIG guess, looks like something used in manufacturing aircraft but could be for any kind of sheet work.

6) Due to the way it is made, it is probably one of many that were used on the same machine.

Physical parameters of the tool:

• Over All Length 15"
• Width 3"
• Weight: 70 pounds
