I found my old (1976 or so) FWB65 that I bought in college. One apt. I had due to unusual layout gave me a good 10m for shooting. Many pigeons also experienced its wrath in my then urban environment. I don't have any .177 ammo at the moment so cannot really test it out yet but surely it will need new seals and probably mainspring. My pistol has the "Sportsman" grip and I would really prefer a match grip if that could be bought. The question is rather or not all the parts can be located and if so would the work be unusually hard for me to do myself? For reference I do tear down and repair/clean camera lenses including Hasselblad. Now if it is more art than science then an experienced smith would probably be smarter. Again, are these pistol easy to put right, and are there any proven smiths on them?
