My first was a Crossman model 140 in the mid 60's. Shot a lot of rabbits with it. Sold that and bought a .20 Sheridan Silver Streak. That one never shot as good as my Crossman for some reason.
Phew... long time ago.. My first was a Daisy model 25. I didn't have it long. When I came home with a nest full of Robin eggs claiming that the mother abandoned them the gun was given to the Goodwill.
