Why no pics of the muzzles if that was your original question?
Or the end of the rib?
No choke measurements either?
I pretty much doubt anyone lopped off the barrels on a best grade Purdey. FWIW
Yes there are people who would do exactly that. I have a 16ga Purdey someone cut off from 30 to 26 inches leaving no choke. Cannot say why they did it, but it did give me the chance to buy it cheap as a project gun into which I added briley thin wall tubes, a light microcell pad to replace a heavy solid rubber pad (to rebalance), a wood refinish, resulting in a good shootable hunter, but not collector gun.
