It is an "M" code (1990) dark blue jumbo joe. I believe they came in black, red, green and dark blue. The lid has orange porcelain enamel on top of the blue. It was a time consuming clean up (very dirty and a lot of rust on legs, bail etc). I kept all the original parts except the handle, screws and wingnuts, etc. So far I've had many college comments(Clemson, Auburn, Florida, Illinois, etc.)
