Weihrauch HW 85 .22

This air rifle is twenty years old. In that time it has never been serviced, probably never seen a drop of oil!. It belonged to my son in law (a lovely bloke but a farmer and as such has little regard for mechanical things. If it works, why touch it?)After it was exposed to condensation and become rusty, he gave it to me to save as long as he could borrow it if needed.
I've done my best and it's looking better. To be honest, it always shot well and continues to do so, a fact that speaks volumes for German workmanship and design!
