Naww..you got the real deal. Faux cameras never seem to hold up to the test of time. Also their serial numbers can validate them easily.
The parts for the old Nikon and Nikkormats have been drying up for decades. Many times it's not worth the time or trouble, even if you wanted to.
The first of the important things that goes is the shutter, which can still be fixed if you have a good independent repair facility. Forget sending it to Nikon (another rat-hole issue entirely) as they are not interested. Repairs to shutters can vary between $100 AND $150 or even as much as $175. The CLA repair (clean, lube and adjust) is always a good recommendation for any camera.
The other important issue is light leaks to the back. No need to explain much there. Suffice it to say, a good independent repair place can modify and repair the back. Rubber or neoprene gaskets can be modified/fashioned if there is a leak.
Light meters by now would have failed and not likely to be worth fixing. Most people don't bother getting them fixed. These all used to use Mercury batteries for the circuitry, but there are newer batt. alternatives for this.
Another minor issue is the gaskets and springs for the mirror area. These crack and you can tell by the slap (or no op) sound. Well, if you need help locating a good repair facility in your area, I can give you some links and leads.
