That was my first thought...but I found where the paint on the rear and front of the guard brace and the backside of guard match the color on the frame very close...it's weird...maybe the guard did not get the same number of coats or the paint batch was different...i dunno.
Most of the bike appears to be catalog original (excepting tires). The seat has no crash rail (as in catalog) so it could have been an OEM 3rd shift seat or replaced later. Everything else including all of the hardware looks unmolested. All of the parts have been on this bike a long time.
