ID for this anvil?

[deloid]

I'm trying to ID my anvil. The overall length is 33 1/2", There are no side markings. The only markings I can find are at the front base "290" which translates to 280 lb or 290 lbs if American pound designation. It was supposed to be 300lb when I bought it many many years ago. It has an excellent bounce of around 80%.
I have attached some images.
Thanks for any help.

According to the book by Richard Postman “Anvils In America” you have a Trenton anvil and the serial # dates it 1918.
