I have a 28-2 that, according to the third revision was manufactured in 1973. I am curious about some markings on it.
The grips are target with black washers and are stamped in black lettering N-RH 5912,N-LH 5913.
Any idea if they are factory grips?
Under the R Grip on the frame is a 7 surrounded by a triangle with rounded corners and a circle with an N in it.
Under the L grip on the frame, in addition to the assy.nr. or whatever it is, there is what looks like I515 stamped on it.
Anyone have info about the grips or markings? Thanks!
