Welding Tips and Tricks

hey guys,
at my old workplace we had a weld el's angle cutting jig for a sch10/40 1.5" elbow that we would use on a horizontal band saw, its a about a 4.5"x4.5" hardened steel that and cut in half and the inside has a 1.5" elbow shaped hole, it holds the pipe by tightening the outer bolts. we insert a pin to locate the correct angle for cutting the elbow, i'm looking to buy one of these, but i dont know what its called, i dont have pictures of this item so i drawed a bmp

if anyone know who makes these i would appreciate the help,

thanks

Thanks alot!
