Newbie needs advice

[jeffjmr]

Picked up this tired looking 1920 DWM police with the intention of making it my son's shooter.

Now having second thoughts about messing it up, so would like some advice as to whether it is most valuable as a shooter, restorer, or left alone.

Broken catch, questionable finish on side plate, later grips, FXO non-matching mag and double stamped second digit of receiver s/n noted. Extractor is worn, but otherwise the bolt parts and receiver are tight. I have replaced a broken catch spring and missing trigger lever pin (someone cobbled in a roll pin) otherwise all else is apparently original. Not the first I've seen with no serial number on the barrel, and hope the experts can comment on that as well as other notable characteristics.

Not sure how many images I can post but mag release, bolt stop, firing pin, safety. trigger and all bolt parts "match" (not the FXO mag). The rest can be seen in the photos.

Thanks in advance for any help.
