Amazon will get you that tool within 2 days. LBS may have a cheap one too. If you use a dremel tool, keep that puller cool, you don’t want to cause the new prongs to become brittle right when you’re really applying some torque.
He'll likely need to use a grinder of some sort, the tool is probably hardened and a file might just skate.

I believe I have at least one of the tools available to use. I will know at 10:00 this morning central time.

Actually I have at least four tools with two prongs that fit your dimensions.

Using a punch or chisel to remove the freewheel will surely ruin it IMO.
I'm hopeful what I suggested above as a start to this process will not destroy the freewheel either. I only want the OP to disassemble the freewheel and post pictures of the inner body mounted to the hub, prior to a removal attempt. I have some specific ideas on how to do this with no damage, but the pictures are key prior to moving forward.

John D if the ring on the Campy tool fits inside the diameter of the inner body, that tool could work.

Of course, you're the expert here. I only wanted to point out that it's not necessarily and always destructive.
As for disassembling the freewheel, I don't think the method you suggested would cause any harm, especially if using a brass punch.

marius.suiram thanks for posting the pictures. Reynolds thanks for posting a picture of the homemade tool. It is along the lines that I've been thinking.

First off, remove the pawls. They should slide up out of the pivot slots. Clean everything. Spray with WD40 should be easy. Special care needs to be taken with the springs and the little pins which hold them in place. Sometimes they are tight and stay in place, other times the pins slide out. You don't want to lose these parts!

Second, remove the axle, etc. You want clear access to the notches. Make a tool to fit the notches. Reynolds has provided a great example. I was thinking a long flat bar which spans the notches and extends a distance to provide good leverage. If you can rig a bolt through the axle tube to secure the tool to the hub, the better. If the tool can be held in a vise, the better.

Third, soak the threads between the freewheel body and hub with your favorite penetrating oil. I'd do this over the course of many days, and I'd heat the freewheel body with a propane torch between applications. This thermal expansion will help the oil to penetrate the threads.

Post pictures and let us know about your results.

Finally, try the tool. The body has normal threads and loosens in a counterclockwise direction. If it does not budge, repeat step three, several more days.

You could make a no-welding-required tool with three strips of flat bar.
You need one strip's thickness to be the sale as the slot width.
That bit won't be strong enough to avoid bending when you turn it.
So the other two bits are sistered alongside, with the slot-width-bit projecting the depth of the slots.

Put at least a pair of holes and bolts each side of the centre section and mount it (or just hold the bits in the proper arrangement) in a bench vice, jump up on the bench holding the wheel-and-freewheel-body, mount that on the tool, and press down HARD on the rim as you turn.

Just to be clear, this is a suggestion for marius.suiram and not for me. Correct?

I was able to take the body off the axle.
Unfortunately one.spring broke and there are some marks there.
I hope I can put it back together.
Thank you for your help, at least I have the hubs.

Well, that's unfortunate.

What you had there is what I call a wide bore 4-speed freewheel. Quite the rare bird.

Folks around here are familiar with a normal bore freewheel, see first picture below. This was pretty much the standard from about WW2, and used pretty much exclusively on 5-speed and more speed freewheels. That's why most people understand it, it isn't really old and janky. 3-speed freewheels were mostly wide bore, see second picture below, from the 1930s up to the early 60s when it went to normal bore. The 4 speed had this run from the late 30s to early 40s where they were wide bore, see third picture. And by the late 40s, it switched to normal bore, see fourth pic. I have only owned 1 wide bore 4 speed, and not from the lack of looking. Too bad you toasted yours.

I think you can rebuild it. The marks can be filed off carefully, as they are in a place that doesn't contact anything; the bearings are the contact surfaces.
As for the spring, you can make one with a strand of brake cable or such.
To reassemble (but probably you already know this) use some thick grease to get the bearings to stick to the races, but not on the pawls (thin oil there). Make a ring of thin wire or tin sheet to keep the pawls compressed while you put the sprockets on.It´s not really difficult.
Good luck!
