Erie 733

I came across this "ERIE" Size 9 pan with a pattern number 733. It has the appearance of a Chicken Fryer as its 3.5" deep. I believe it's a ribbed handle. I can't find that pattern number in any of the literature I have. Can anyone tell me about this pan. Thanks

BB lists 733 as the p/n for a #9 deep skillet.

Thanks. Is it particularly rare or hard to find? I appreciate the information
