RWS Diana 75 10-meter target rifle / air rifle / West German Olympic sport rifle. To reattach the Scope use a 9/64 L Wrench to do so. The one used is an EKLIND 51909 9/64 Inch Cushion Grip Hex T-Handle T-Key Allen wrench. This air rifle is not fully functional as it will require a new.Breech seal, that while hard to come by; can be replaced by a rubber plug or an old cork bottle stopper made by yourself. The original has rotted away, and I have no idea where to get another one. As a side note, the cheap Chinese made scope cover seen in the first two photos snapped during packaging and is now broken and will need a replacement. As a bonus I have found a small packet of pellet's for this rifle that will be included with the rifle. This item is in the category "Sporting Goods\Outdoor Sports\Air Guns & Slingshots\Air Rifles".
