brace height on a Bear Cub

[chinook907]

Hey guys.  Just got a beautiful Bear Cub for my wife a 69 (?),#9P6806B 35@28", 60".  Kindof a double shelf, has a plastic pin coming out each side of the riser, beautiful red glass on both sides.  Wondering where to start for brace height.  Thanks for the help, and any other info you might have on this type bow.

String length 3" shorter than the the nock to nock. This was a semi-recurve if I remember correctly.
8-9"
