According to Reddit, this week's exchange includes:

M1907 SL

M1897 Shotgun

Grappling Hook

Landship

@mrtnm1994117another week of skins I already have...

What does someone needs to do to get the sjogren 😢

The 1897 had to be 2 months ago 

This seems deliberate now 

This game is on its last breathes

I created a more spectacular calculation for Sjögren Inertial Shotgun.

self-loading rifles Winchester Model 1907 and shotguns Winchester Model 1897
What is the probability of the "Winchester" week (both selected guns are manufactured by Winchester)?

The "Winchester" set has only 3 elements: M1907 Selfloading, M1897 Shotgun, Russian 1895.

The "International" set has 69 elements: Model 1900, Model 10, M1897 Shotgun, Sjögren Inertial Shotgun, 12G automatic, Ribeyrolles 1918 Carbine, Hellriegel 1915, SMG 08/18, Annihilator, MP18, Automatico M1918, RSC SMG, M1917 Trench Carbine, Maschinenpistole M1912/P.16, Farquhar-Hill, Mondragon, RSC 1917, Selbstlader M1916, General Liu, Howell Automatic, M1907 Selfloading, Fedorov Avtomat, Cei-Rigotti, Model 8 Autoloading, Selbstlader 1906, Chauchat, Parabellum MG14/17, Lewis gun, LMG 08/18, M1917 MG, MG15 N.A, BAR M1918, Madsen MG, Perino Model 1908, Huot Automatic Rifle, M1909 Benet Mercie, Lebel Model 1886, Mosin-Nagant M91, SMLE MKIII, Martini Henry, Ross MKIII, Gewehr M.95, M1903, Vetterli-Vitali M1870/87, M1917 Enfield, Gewehr 98, Type 38 Arisaka, Russian 1895, Carcano M91 Carbine, P08 Pistol, British Bulldog, Frommer Stop, Auto revolver, Nagant Revolver, Mars Automatic Pistol, 1903 Hammerless, C-93 Pistol, Repetierpistole M1912, Revolver MK VI, C96 Pistol, M1911 Pistol, NO. 3 Revolver, Howdah pistol, MLE 1903 pistol, Bodeo 1889 Revolver, Modello 1915 Pistol, Obrez pistol, M1914 Taschenpistol, Kolibri pistol, Gasser M1870 Revolver.

If the set has n elements, the number of k-combinations, denoted by C(n, k) is equal to n! / (k! (n-k)! ).
The "Winchester" set has 3 elements, the number of 2-combinations, denoted by Winchester(3, 2) is equal to 3! / (2! 1! ) = 3.
By name the first possible pair is M1907 Selfloading - M1897 Shotgun (THIS WEEK), the second possible pair is M1907 Selfloading - Russian 1895, and third possible pair is M1897 Shotgun - Russian 1895.
The "International" set has 69 elements, the number of 2-combinations, denoted by International(69, 2) is equal to 69! / (2! 67! ) = 2346.

The probability of the "Winchester" week is equal to Winchester(3, 2) / International(69, 2) = 3 / 2346 = 0.00127877237
And the probability of the "Sjögren Inertial Shotgun" week is equal to NoSjögren(68, 1) / International(69, 2) = 68 / 2346 = 0.02898550724

The probability of the "Sjögren Inertial Shotgun" week is TWENTY-TWO times the probability of the "Winchester" week (68 / 3 = 22.6666666667).

I wonder why the Landship appeared in the weekly scrap exchange after a year?
