Looking for a Ruger Old model (3 screw) Barrel

[Corporal Capps]

I have one old model (3 screw) 6 1/2 inch Ruger Blackhawk and one 4 5/8 inch Ruger blackhawk. Would like both to be 6 1/2 inch. Need a 6 1/2 inch 357 barrel or if someone has a 4 5/8 and would like a 6 1/2 I can do the swap and fitting. New Model barrel will not work.

Well as normal my typing was not very good. What I meant to say I can swap my 4 5/8 for your 6 1/2.
