There are only 2 different hosels: the Z1 has a shorter hosel and the 2 and 5’s are exactly the same length. Mine is 69* and has the standard 2 and 5 hosel.
Just had mine measured- it’s at 69* and all the toe wants to do is point straight up. Do the spinny thing and it goes toe up right away- even sits that way in the bag with the head over on. I don’t think the mad scientist Guerin Rife would make them adjustable 2 degrees from 69-71 and not have them stay zero torque.
No idea who makes them.
They are definitely personalized one offs- Little Silver, NJ is a small town. The “Have a nice round” sign looks like the Batusrol emblem. And 2 Rutgers emblems- but no sign of who makes the head covers.
I looked up on their site the custom order options and the lie angle you can order is 69-71. So I suppose you can’t get any flatter than 69 or upright than 71, but the lie angle can be adjusted.
