Hi Mark, the angled sides are typical of the "Kast Console" line stoves.
The currently available Kast Console II is the closest to what you have. The biggest difference besides the old style Triburner stoker system is the lack of ornate cast iron pieces on your stove, also the style glass for the door on yours has a notch cut out of the corner because of where the latch is placed.
BTW I have a grate and hopper for your stove if the person who purchases it is interested. Best wishes for a speedy sale!
