These are companies that do not specifically put out wrestling videos.
Still, some have put out a tape or two some might find worth watching.

Academy Men

Bondage, discipline, and humiliation all combined with the uniformed men of your choice.

Sadly, 2003 wasn't a good year for The Academy. Their founder passed away. But a devoted crew is keeping his dream alive and the cameras rolling.

Chained Heroes

Beefy guys get beat up while in bondage.

Heroes in Chains

Interrogation is the only thing on these guys' minds.

Grapik

This bondage tape company has a few wrestling related video. Unsure how much wrestling there is. But if they're anything like Can-Am's similar combos then it would mean there's a lot more bondage than there is wrestling.

Manhunter

Manhunter videos cater to bears and lovers of the 'everyman' look. They have a few grappling tapes ranging from apartment wrestling to construction workers.

Palm Drive

Palm Drive is probably the most artsy of any company now in existence. And why shouldn't it be. They're probably one of only a select few gay tape companies run by someone with a doctorite! Jack Fritscher is not only the director of Palm Drive, but he's also an award winning author and gay historian. If you haven't already done so, go to your local library and ask to see a copy of Arena of Masculinity. He can explain himself better than I ever could so here's the link to his personal site.

P.R. Simon

This company puts out videos which are chub releated. (For you neophites: Men who are overweight.) They have put out three sexually related wrestling videos.

Sharpshooter

This muscle-watcher company has come out with a few videos which have included wrestling and boxing. The titles include Buff Bad Boys Boxing Club, Greek Games 2000BC, Naked Cage Fighters, Wide Nude World of Sports, and Naked Muscle Warriors (which has 'resistance' wrestling).

Shotgun Video

This hardcore bondage company specializes in testicular torture. (translation...major ball bashing.) To date, they only have one video with a wrestling related scenario: Winner Take All starring Jake Hunter and Jeff Hilo.
