What is the pitch of thread for a .44 Super Blackhawk barrel? Thank You

Super BH & Blackhawk barrels, all calibers, new and old model (large and mid frame) are:

24 TPI x .685" (11/16), (shank .618".) (same as 3rd Gen. SAA Colt)


SBH Hunter barrels are the exceptions: thread count and diameter varies:

.41 SBH Hunter is 32 TPI x .708" (shank diameter is .623"),
44 SBH Hunter is 20 TPI x .747" (shank diameter is .680"), (same as Super Redhawk)
.45 SBH Hunter is 32 TPI x .703" (shank diameter is .623").
