I finally managed to track down a company that in the 1930's owned the one that made my anvil, I wrote to the company president about my dilemma in Identifying my anvil and here is what he wrote back.

I've only worked for Hanchett for approximately 34 years and during that time I've been told that Hanchett purchased
the Covel Company sometime in approximately the 1930's. Wha you have is a sawfiler's anvil. It is used for leveling and
tensioning circular saws. Based upon the photo it appears to be rather large in size. We still provide anvils on a very occasional
basis as there are a number available from auction sales. As an example for value, a 14" X 16" X 5" Crowned face anvil currently sells new for $4,575.00. Please feel free to visit our website at Hanchett Manufacturing -- Knife Grinding Systems - Band Saw Sharpening Systems and review our current products.
Thanks for your interest.
So there we have it, A sawfilers anvil, a rarity apparently if I am reading this correctly. I got lucky.
