A1 Free Sound Effects was a website with stock sound effects, they could be downloaded or a CD ordered. The owner of the website died in 2011, and the website doesn't exist anymore, but there are archives of it.
This is the only remains from the website.

Most of these sound effects can't be downloaded anywhere anymore.
