To clarify, I have no history on the gun before I took possession. Looking at the damage I speculate that it at one time got the heavy crease/dent and was either fired in that condition, or a poor attempt to push the dent caused the crack.
Yes, the vertical defect is where the crease dent was. I do not see any cracks formed perpendicular to the linear crack. Hopefully this evening I will try to get wall thickness measurements of the tubes FWD, AFT, and at the damage point. Running a tight patch through the bore, there is no loose spot as when a bulge ring exists.

Several years ago Buck Hamlin welded a 16 gauge Lefever barrel for me. About a 3/8" crack about 3 or so inches back from the muzzle. I'm not sure if I can find the crack now.

Results of the wall thickness measurements. I took measurements one inch forward, one inch Aft and inline with the crack. The thickest area was near the top rib and measured 0.038"-0.040" at all three points. The thinnest walls were near the bottom rib measuring 0.030"-0.032". In line with the crack the measurements were 0.034"-0.035".

That wall thickness should be fine to weld. The use of a well fitting copper bore plug will minimize the intrusion of the weld bead into the bore.

And, as the late great Running with the fox mentioned, put a rubber plug in each end of the tube and let alet an inert gas flow through the tube while you weld it.
Prevents sugaring (oxides)
Out there doing it best I can.

Thank you to everyone that provided guidance with my dilemma. I will turn a copper plug and try to locate a magician with a tig welder.

I’m doing the same kind of job on a lawn sweeper frame that somebody (me) hit a tree with.
Definitely a tig job. Not a stick job
I used a series of sockets to swage the tubes back to round. Planishing as I went.
Final fit up is tomorrow
I may gas weld the tubes back together.
Out there doing it best I can.
