This is a mid 90s vintage German made Weihrauch model HW35 air rifle. It's in .22 caliber and has a very nice walnut stock. This gun is also tuned with a special spring, spring guide and piston seal for a very smooth, low recoil shot cycle. This gun also has a very nice copper bronze aftermarket trigger blade with two adjustment screws. This gun is very, very accurate and modestly powerful. It will shoot a 14.3 grain pellet at just a little over 600 fps. Selling for $500 shipped or will trade for tesoro. I would also sell for $460 with the original OEM trigger blade. I have a tesoro outlaw in mind, but you may have to add some cash on your end. Let me know what you have.
