Won on Ebay on Sept. 08, 2013 for only $14.99 plus shipping of only $6 as it shipped with the Lodge No. 3 I bought yesterday from the same guy, Ernie, in Bryant, Alabama. His ebay name is iamthewann. On the bottom is incised USA DP 4L3 at the end opposite the current version of the Lodge logo.
Ernie responded to my question and said that this pan was cleaned and seasoned at the Lodge factory where he works. He also said: this is an early version made in the 1980’s; seasoning at Lodge was by spraying with vegetable oil then into an oven for 45 minutes up to 650 degrees.
