I just picked up a Model 90 6 shot and according to Taurus website it was made in 1986. I don't think it has ever been shot or if it has very little. Does anyone have any info on this revolver? I have checked Taurus web site and no reference to it at all and a goggle search came up with nothing. It looks very similar to a Model 83 in .38 Spl. I need a new rear sight blade, the original one has been lost and I need a replacement. I looked on Numrich Gun parts and they have a schematic of a Model 90 but the rear sight looks different than the one I have so I am not sure if this one has been changed or if it is the original one at all. To me it looks more like a S&W rear sight. Any help would be much appreciated.
