Can anyone help me identify my 3 legged dutch oven, and possibly age? It is 10" across, 6-1/4" high and 4-1/2" deep. The legs are 1-5/8" long. The only markings are the 10 IN on the lid, and Made in USA and 10 on the oven bottom. I thought that it might be a Lodge, but then I saw some old Griswolds with similar style. I think it is fairly old, but I cleaned and seasoned it. Hopefully, the pictures I took will upload properly, I am new to digital, and have a lot to learn.
