Old guy here. Soon to be 66 years old. My first foray into catfighting was an 8mm
film from California Supreme. It was this cute girl named Tene vs some older
brunette and it was TOPLESS. Then some time later I ordered a color 8mm reel
that featured a series of nude female combat vignettes. The first was a nude wrestling
match between Little Vicki (short redhead) and Belinda Superboobs (older brunette with nice natural jugs)
After that there was a nude wrestling scene, a nude sumo scene, nude boxing, and a nude roller
derby scene. I am pretty sure it came from Superior Studios. It became sort of legendary in my
dorm at college and guys would meekly ask if I would break it out to screen on drunken nights.
In the eighties before VHS took off I bought some SPECTRE films that were from Roselyn News.
You can find them on the tubepornclassic site.
