I just was told by my pal that the inside is flawless so I'm heading over in the morning to see it. I've never bought a DO having focused mainly on skillets and one great deal on a pair of ERIE eccentric kettles. Thinking this might be a Christmas present for my wife. That solves two problems right there. No trivet. How can I tell if this is an original lid and bottom set?
I'd say you probably can't tell if its an original lid and bottom set. Griswold mixed and matched them for their orders all the time. If they shipped a number eight dutch oven, all they needed to send was a top and a bottom and it was good to go.
Griswold is good for matching lids and bottoms up, Wagner will make you pull your hair out. For instance a Griswold number 8 skillet cover will fit number eight regular skillets, its that simple, no so with Wagner.
I started collecting DO's a long time ago and have several and still buying them, my latest just yesterday.
From what I see of the DO in question here, it looks to be in pristine condition. If I wanted a number eight Griswold DO, I'd jump all over that for seventy-five dollars.
If you wait around and look and look and search, you can probably find one for a few dollars less, but I don't think you are going to find one much better than this one, IF, you find one better, especially since your friend said the inside is so good.
My problem is, on some things anyway, I have the pristine pieces for show and the dogs I cook in. If I had this piece I think I'd make it pristine and set it on a shelf, and then go buy me a Wagner DO for way less, and cook in it. ;D
