Joseph Lang and Son 360 Nitro Express #2 Double Rifle and accessories

I have a Joseph Lang and Son 360 Nitro Express #2 double rifle with scope, case, ammo, does, brass, projectiles.  The . 360 No. 2 Nitro Express fires a . 367 in (9.3 mm) calibre, 320 gr (21 g) bullet at a velocity of 2,150 ft/s (660 m/s).  Rifle was hand made in England in 1906.  I'm interested in trading for a Rolex watch, possibly another brand, etc.  I put 9.3 X 72R as the caliber size because the drop down menu does not have a 360 nitro #2 option.  Also, the make is Joseph Lang and Son.  The picture with the two rounds side by side is for comparison.  The round on the left is the 360 Nitro #2, round on the right is a 338 Lapua with a 250gr Scenar projectile.
