Compare the barrel on my stock 686, the rib is the same thickness, someone with enough machining finesse can do the work. The barrel rib could have been widened when vents were machined in.
An example of that kind of work is the vent rib I had machined into a 5.5" M41 barrel by E.W. Kovachic Technologies.
The font on barrel roll marks of the OP's gun looks correct for a S&W barrel, they match mine. The bolt pin position and the weep hole on the underside of the barrel lug all look S&W.
What's intriguing to me is the military "flaming bomb" proof marks... anyone recognize them?
