I am new to these airguns but was interested in restoring this old airgun of my dads for my son. I am unsure which variant it is and was wondering if any of you experts could point me in the right direction as to year of manufacture, variant, place to buy a replacement fore end etc. The only numbers I see on the gun are "111" at the end of the pump cap. I see no serial numbers on the gun. The "wood" parts seem to be made of some kind of plastic. Thanks in advance for any help!
