Recently got a new anvil; however,  after going over it with a drill with a brush attachment and giving it a 24-hour vinegar bath I can't find any markings. The only information I really know about it is that it is 130 pounds. I've also noticed that it seems to be a colonial style anvil, unfortunately, that is where my knowledge ends. Hopefully, you guys can help identify it. Any help is appreciated, thanks in advance.

Where in the world are you & your anvil located? Have you read this yet? READ THIS FIRST

Given it's location and apparent age, I would guess a Colonial anvil also. It looks like a nice find and has many decades of life left in her.

there certainly seems to be the remnants of some writing on there. 

Maybe try rubbing with some chalk on the surface to see if it makes it easier to read?

Some of the old hands around here probably have a better way of bring it out.

 

Pencil rubbing of paper may expose some information. Dust it with chalk, flower, etc and lightly brush off the excess leaving the indentations with dust in them. Use a strong light from a low side angle.

No matter what the results it is your anvil so use it. A name stamped into the side of an anvil does not make it preform any better. Get to know each other and listen to the anvil. It will talk to you once you get acquainted.

Hot metal will shine up the face like nothing else can.

Just gave it a go with just chalk and paper and didn't get much, I'll give this other method a go, thanks.

I have two colonial anvils I cannot identify, other than the fact they came from a shop in Herkimer New York from 1781

Most colonial anvils are not marked and cannot be traced to any of the hundreds of makers that made anvils over time.
