It looks like it belonged to a sea captain, who had a little too much time on his hands on a bad run of fishing...but had a welder on board to occupy his time. There is such a consistent pattern of rust, it had to be in sea air one would think.
At least there is no shortage of op rods and springs at the moment.
What are ya gonna do? I am sure that stock will meander over to something more worthy...but this thing is screaming for, help.
