Wow! The barrel nut looks messed up too. I'm not sure you could get it apart with a normal barrel wrench. The ported barrels can be a real mess if somebody shot a lot of lead in the gun. The lead will pack in the void between the barrel and shroud. I've had to tap them apart with a brass rod shoved into the ejector rod cutout in the shroud. Somebody who was an idiot put the barrel back on, but didn't thread it all the way back into the frame, then they ran the barrel nut down way too far and probably used a small screw driver and a hammer or something to jam it tight. Be careful with this one. Plenty of other DW 44's out there with less questionable histories. Also, the rear sight screw should be an Allen head.
As was also pointed out, the extractor star appears to be messed up/chipped on the ratchets.
In addition, the turn line on the cylinder is pretty erratic, and the red ramp is starting to walk out of the front sight.
I would say this might make a good parts gun, though I'm not sure what parts would be useable.
