I have a brass ScubaPro SPG 0-5,000lb made in Italy. It does not go to zero when the air is off or dissconnected from the tank. The dial sets at around 300lb. Is there a waay to fix or is it trash?

Some screw on and some are crimped on. With nothing to provide a grip, that one is probably crimped so it is probably toast.
If it were mine, I'd have to play with it a bit. I suspect the failure you describe is probably caused by some binding in the mechanism that operates the needle. (Which also suggests that water got into the case.) I'd have to drill a hole in the back of the case and give it a squirt of WD-40 or something similar just to see if that fixed the problem. It might even be possible to remove the blowout plug rather than drill. I expect that plus is theoretically replaceable...
