Number 7 in the list of regulators should be the right one.

 Harris F series torch mixers and associated tips are what we are talking
about here. Harris sells torches that are modular. A torch body has the
valves and gas fittings, a mixer where the oxy and fuel are combined and a
tip tube to get the tip out where you want it and finally a tip.
What I got was a 19-6 torch body, a H-16-S mixer, a DC-50-C tip tube and a
1390-B heater tip.

The larger torch body the model 50 has the built in pilot that is on the
AllStates torch and may be the same torch body. It also can mount a Type F
mixer. They have quite a few combinations of torch and type F mixer in their
catalog.

The parts are available from a variety of online welding supply companies.
As for the regulator what you want is a standard low pressure propane
regulator like what would supply a house. They provide propane at about a
max of 11-14 inches of water which is about 0.5 psi of  pressure and can be
adjusted down if necessary and if sized properly provide more than adequate
volume of gas. If you use a standard high pressure regulator on this torch
you negate the special way the mixer works. Using a low pressure regulator
the torch will pull all the fuel it needs from the regulator assuming the
regulator is big enough by creating a vacuum due to the venturi in the
mixer. This means once you set the initial fuel flow you only have to adjust
the oxygen valve to change the flame size.

 I bought this regulator which is more than adequate for this torch.

This torch puts out a lot of heat, I lost my focus this afternoon and melted
a piece of 3/8 square stainless today very quickly.
