Craig, I would likely agree that it 'may' be a recast.....
But I would like to see it cleaned up to verify.....
Bottom gated items were produced by 'some' up thru the 1940's.
The Casting Quality will likely tell the story....
There are plenty of folks that play around currently with backyard/shop projects 're-casting' older items .... (meaning using an original skillet as their 'pattern'.... )
Lots of these fellas can be found out on youtube......
PS... I uploaded pics directly so this post will remain valid if the server you are using goes poof down the road.....
