Weihrauch for air rifles are as follows: 'E' (Export) rifles typically have American-specification walnut stocks with white buttplate and grip-cap accents, and factory-fitted sling swivels. The barrels of 'FSB' (Fully-shrouded barrel) rifles have an outer shroud (sleeve), internal baffles, and larger overall diameter. This is intended as a more compact, albeit less effective alternative to a screw-on or slip-on silencer, which would add extra length to the rifle. 'K' (‘Kurz’, German for ‘short’) rifles have a carbine-style barrel that is shorter than the barrel fitted to the equivalent full-length rifle. When applied to the HW 97, 'L' signifies 'Lang' (German for 'Long'), denoting a 385mm barrel. On all other rifles, 'L' signifies a 'Luxus' (German for ‘luxury’) rifle with a stock finished to a very high standard, usually from Walnut. The ‘LS’ (‘Lockschaft’, German for ‘thumbhole’) suffix was only used on HW 35 models equipped with a thumbhole stock. On all other Weihrauch thumbhole-stock rifles, this suffix was replaced with ‘T’. The 'M' (Match) suffix was only used on HW 55 models equipped with a match-style stock. Where basic HW 30 M/II and HW 50 M/II rifles are equipped with the unadjustable ‘Perfekt’ trigger, an 'S' suffix signifies an upgraded model fitted with the fully adjustable 'Rekord' trigger. When applied to the HW 55, ‘S’ means 'Sport', signifying a plain Beech sporter stock. 'ST' signifies a synthetic (plastic) stock. 'STL' signifies a barrel, receiver and cocking lever in a light silvered finish of electroless satin nickel plating instead of conventional blueing. Note that this suffix does not, as is commonly assumed, mean ‘Stainless Steel’. When applied to the HW 55, 'T' means 'Tyrolean', signifying a Tyrolean-style curved cheekpiece stock. For all other Weihrauch rifles, 'T' signifies a thumbhole stock. Air pistols Weihrauch Patent information Selbstladepistole mit Spannabzug. Veröffentlicht am 4.
