Mystery Socket Rail Brand

Hey does anyone know who makes this socket rail? My grandfather just gave this to me and I’m curious if there is somewhere I can buy more of. The unique trait of this rail is the press to release. Sockets are great neck if that helps. Thank you in advanced.

 

Star or Torx bits. Had to buy some like 30 yrs ago to get the Ford calipers off.

 

Never seen a rail like that, now I’m curious. Any markings on the rail or sockets themselves that might give a clue?


Edit: nevermind: “Great Neck” is visible on the bits. Do you know if those bits originally came on that rail?

 

Looks like it was a design that only came on older versions of Great Necks socket sets. Found these on eBay:




Found a company called Jetech on Amazon that still uses the design for their sets as well, but nothing for the rails without sockets.

AutoZone used to sell GreatNeck brand.
Or at least they did when I worked there anyways.
