Genuine Nikon Nikomat/Nikkormat shutter assembly fits all Nikkormat/Nikomat including FT, FTn, FT2, and FT3. USED part, Excellent Plus condition. Sold as pictured. I have charted the shutter accuracy, and provided that information. Most of the shutters I have tested in the last 15 years perform about the same. The 1/1000, and 1/500th are generally slower than specs but can be compensated for that. I do not sell shutters where the speeds are erratic. Plus, I do not recommend adjusting the shutter unless you can measure the curtain speeds.  Made by Nikon Japan.
