Definitely a Fisher. That's an eagle clutching an anchor, right? The bolt holes, as Sam pointed out, are also a giveaway. There's probably a "10" on one of the feet designating its 100 pound weight.
Fishers are good anvils (I have a nice 300# Fisher), made with a cast iron body and a cast steel face. They don't ring loud at all but they rebound nicely and never get swaybacked like the old wrought body anvils. This one looks to be in nice shape too. Good score.
