I have the 500 also, got it for Christmas when I was 12 or so. There must be a few thousand bb’s in the pond in front of the house. It sat for a long time as life went in many directions but when I got it back out it did the same thing, just leaked down and didn’t seal at all. I found a local repair place and he brought it back to life. I think there is a rebuild kit available. It’s funny, I once built a small block 350 in my kitchen because that’s what kitchens are for, I can fix a lot of problems in the average private aircraft but I can’t do gunsmith work at all. You’ll enjoy this when you get done. Wally World has good pricing on 12mg CO2 cartridges. Treefrog I went to that website you linked and clearly I’ll be going back. Looking at all the corrosion makes me wonder if Crosman had any idea then that many of the guns in this price range would still be around this many years later. I wonder when the 500 went out of production?
