Anyone into Vintage Air Rifles?

[Orlando]

A buddy of mine called me up to take a look at a Air Rifle he inherited years ago. Its a Walther LG 55 made approx 1960. I have been searching the internet but there is no info on dissasembly. Parts are no longer available (besides seals and springs) so I am alittle worried about tearing into it without some guidance. Anyone know anything about these rifles?

yes, very nice looking air-rifle..Does it still shoot? If so Just oil it, if seals are out, that is another thing..

My buddy said the seals are bad. I havent really messed with it yet. If its a leather seal may get away with just oiling it. If silicone seal it probably needs replaced
From what I hear there is one part that can be real tricky installing and easily broke. I break it and I'm screwed as parts are not available
Thanks for the links.
