fireforged

I am new to this site and I am looking for some help in trying to identify my anvil. It belonged to my great grandfather and we believe it dates back to late 1800's or early 1900's. I believe it is an Arm and Hammer brand not sure, very worn around stamp. It has number 30821 on the right side of foot. It has 108 stamped below trademark. I am attaching pictures. If there is anyone that can help it would greatly be appreciated. Thank you.
