Almost 3" of drop there, Greg. That'd be a problem for me and, I think, for quite a few other shooters used to modern dimensions. I also wonder why the L barrel measures .730 and the R barrel .709. Almost sounds like he measured choke in the R barrel. But if he did, that'd mean the L barrel is cylinder, based on standard 12ga bore diameter. But it's marked 13/1 on the flats, which means standard bore diameter ought to be .719. If so, that'd be .010 constriction in the R barrel and over .010 honed out of the L. I'd ask some question about that if I were really interested.
