Ramp front sight on a early 92 src |Winchester Sights|Forum|Winchester Collector

A friend has a nice early 92 src that has shinny metal except the barrel that has almost perfect dark blue and a “ramp” front sight. It is all correct including the rear sight. I believe it was rebarreled  by Winchester because it has “P” (in a circle) stamped behind the VP proof mark on the barrel. 

  I would appreciate any input on this ….. Does it devalue it or increase the value ?  It sure looks odd !!

Thanks Mike
