It would help if you stated the condition of the rifle.
These are extremely valuable air rifles even in poor condition. They only made 200 that were the model 90's. It had a diopter rear sight and interchangeable front sight, The stock was made of Walnut. Please state the condition of the rifle (Is it complete? ) so I can give you an estimate of value. Rate it as poor, Fair, Good or Very Good. Falke was only in business from 1951 to 1958 in Germany.
If you are asking about the Falke Air Gun. The price would be about $100 to $250, depending on the condition of the gun. You can usually add about 10% for the box.
