The robotic, piston-based sex machine that can be outfitted with a dildo and other accoutrements sold.

The mattress outfitted with chains is still available.

Kink.com's first prop sale earlier this month was a success and many of the most titillating items used in filming porn sold, but there's still plenty to buy at the upcoming sale on Sat., July 15, and Sun., July 16.

"There's new stuff, and some of the items that were available before are still there like coffins and a massage table," says Kink.com spokesperson Mike Stabile. "We went through our wardrobe department this time and so there are a lot of costumes."

Costumes are of a higher quality than what you might find at a Halloween store, Stabile says, and include football and lifeguard uniforms, capes, speakeasy dresses, Wonder Woman fetish boots and Roman and gladiator costumes.

"Usually what we do is we try to be authentic," Stabile says. "These aren't things that look cheap."

After purchasing the Armory for $14.5 million in late 2006, Kink.com ran a porn-film studio for 10 years, as reported previously on SFGATE. Earlier this year, the company adjusted its business model, moving operations for the online site and film productions to Las Vegas and turning the Armory into an event space and corporate offices.

Now, in a series of sales, the company is selling off the vestiges of its San Francisco productions. Interested shoppers can drop by the sale at the Armory on Saturday and Sunday between noon and 4 p.m.
