15901 was an O grade, straight grip,#2 frame,29in barrels,unstruck weight of 4lbs 4oz. Someone wanted a LIGHT 10ga. Bought as a parts gun for $169. Good frame and action parts,barrels are literally sewer pipes. Mayb I'll make wind chimes out of em!
No evidence of barrel lug being reworked,probably couldn't tell anyway if they were refinished at the same time. I suspect forend wood was just modified to be used with the new style latch from day one.
