colt 1892 antique

I have a colt 1892 up for grabs today, antique status chambered in 41 long colt, built in 1896

The finish is gone around the cylinder with minor pitting on the top strap. The wear pattern on the finish almost like the finish was stripped with acid or something, everywhere else is a gorgeous shiny blue.

The gun cycles and locks up well, however it needs a new hand spring. It works 95% of the time as is, but if you point it straight up the hand won't rotate the cylinder due to the broken spring. 

Comes with 3 sets of grips, one brand new pachmayer set on the gun, a set of wooden python grips(need fitting) and the original wood grips.

Asking 4500 plus shipping

Selling because I want the 4 inch version instead
