I've done some looking and seen a Max 2 Sporting Clays with an adjustable comb, but that comes with 8 chokes.
There's also a 3T Paradox that's sometimes listed as a trap gun, but no adjustable comb.
Add to that a synthetic-stocked clays model with adjustable comb, and you get a glimpse of the huge number of models and variations Fabarm has offered over the years.
Because yours has the case but no extra tubes, I suspect it's incomplete. You can get tubes from Briley, but you might want to factor that in before deciding to buy.
