LOL Tickling Bell Game Clips

I absolutely adore these clips!

First off, can anyone guide me to the complete catalog of bell game clips?

I know there are at least two or three.

Also, does anyone know the back story on these? My imagination says that this is a group of attractive upper middle class suburbanites, somewhere in the Midwest, who just happen to be into tickling. The masks to “protect the identities of the innocent” and tickling reactions make it all seem so genuine!

Thanks for any guidance!

The Bell game is my absolute favorite set. If anyone has them or knows where I can buy them all, I will pay.
