I would have to see the first one to beleive it. I have never seen an offset Joes thicker than 1/4. Needless to say if it were older I could beleive it was a custom made but by 2003 you had no options, no ordering, 2 sizes what you see it what you get with OK Joes by then.
Oklahoma joes sold out to new Braunsfels in 1998 which had been sold to Charbroil parent company WC Bradley CO in 1997.
Sadly there is very little info on when and where the swithover from 1/4 to 3/16 then to 11 and 12 guage sheetmetal happened.
With all that being said if its 1/4 or even one of the NB/CB 3/16 ones its worth the $400 IMO, not so much if its the sheetmetal version and this size is $399 brand new at academy. Looks just like what was sold at academy as a Ok Joes Longhorn, now selling as New Braunsfel longhornhttp://www.academy.com/index.php?pag...263-02219-3369
Not sure if they have improved them with the name swithover but I looked at these 2 years ago and felt like it was a travesty to the OK Joes name, cheesy bolted on firebox and 12 guage sheetmetal.
