You have 3 choices. 1. The 760 is an inexpensive air rifle and might not be worth repairing. It may be cheaper to purchase a new one. 2. Crosman offers a service to locate repair shops that service Crosman products. But it may cost more than a new rifle. (see the 1. link below) 3. Repair it yourself. Crosman still has parts for this rifle, But there are 10 different models of this rifle. So you have to determine which one is yours. Down load the parts manual first and locate your part number ( See the 2. Parts manual Crosman link below.) then contact Crosman and order the part (see the 3. link below)
If it's still under warranty I would send it back to Crosman or at least contact customer service at Crosman. WWW.Crosman.com
The Eine Milliarde Mark Berlin can be worth up to 1 million dollars. It all depends on what shape it is in.
