I have a G80 which has not been fired for 30 years. Decided to try shooting again, so have ordered new breech seal and leather piston washer. Have looked on YouTube re strip down video, but none available. Are there any similar models I can look for to safely release spring tension? Also, how should I pretreatment leather washer before fitting? Thanks.

Hi, I have a G80 that has not been fired for nearly 30 years. I have ordered a new breech seal and piston washer as these are probably toast. Any recommendations on how to release spring tension? I have looked on YouTube and there are no G80 video's. Are any other models similar? Also, how should I pretreat the leather washer?
