Closest thing I'm aware of is the Trijicon Accupoint 1-4x with their single vertical post.

Burris offered post & crosshair up until the early '90s or so and you might watch Ebay for a used one. I have one in a 4x on a Marlin .356. Of course Weaver and Bushnell offered them back in the day as well.
