Now, is that what you observe? Schwing's chart says a G2133B should be a standard gun with 30" barrels and M/F chokes. Schwing is not the last word... I'm not sure Cody is the last word. What you see on inspection may be different from either, and you get to decide if the gun was modified or not. Some custom work is very, very good and difficult to tell from original.
Barrels are rust blued, frame is Du-Lite hot blue. Professional evaluation may well be worth the money. If buyer is unwilling, simply walk away and keep looking.
