When John Beechem saves the Maharajah and his party, John gets off his horse and grabs a rifle complete with shoulder strap from his horse, but that rifle turns into a pistol when he meets the Maharajah, before he(John) gets shot.
Beecham's tooled leather saddle is lovely but inaccurate for 1795.
The Agra Diamond is pink. The one seen on the show is not.
