Where to get narrow pistol grip handlebars so my palms face each other?

I saw a chopper in a video a while back, not on a big dog, and wish I'd bookmarked it but the handlebars were rabbit ears to the extreme.
The rider was basically holding grips that were completely perpendicular to the ground, no angle whatsoever.
I always liked the aesthetics of those bars but never thought of pursuing until recently I hurt my rotator cuff and can't do palm-outward pull ups but I can crank out palm-facing each other pull ups just as comfortably as before.
Hence now would be the perfect time to look into getting those handlebars but not sure what they're called or who makes them.
Any ideas?
