I don't know that particular anvil, but an excellent book about anvils, "Anvils in America", is available from:

Richard Postman
10 Fischer Court
Berrian Sprongs, Mich 49103-1210
(616) 471-5426

And now that I think about it, there was an "Arm and Hammer" anvil company at one time, so perhaps that is it. Give Richard a call and he can tell you.
