Wapak Double Burner Griddle

I found this beauty today at an antique store for 20 bucks. Obviously I know who made it. Any further info about manufacture dates would be great. Also, a possible value would be nice as well. Thanks y'all. Happy picking!

The BB identifies it as a long griddle, New England style. 1903-1926. Places a value of $60, but the BB is old and value is what someone is willing to pay.

Very nice find.
