need help identifying a cast iron skillet

[RandyW]

I just bought this cast iron skillet paid over $100 for it and have no clue as to what it is the only marks anywhere on it are on the bottom, a 12 at the top with a smaller 3 at the bottom I will attach some pictures

Unmarked Lodge, 40s-50s. Required reading here: http://www.castironcollector.com/unmarked.php

I would even narrow that down to 1950s. A #12 anything in good condition is a nice find, but $100 is unfortunately about double the value on this one.
