Sweet finds, Jeff! The Go Anywhere was a promotion from collecting Marlboro Miles. I have a nice Victorinox watch from collecting those.
I'm guessing you are probably right on the 'O' code lid being a mismatch from the MBH.
Does the E code SJ have a single damper on the bowl, or 3 dampers? I have a C code SJ that has 3 vents on the bowl that are all E code.
Looking forward to seeing some pics!
