Nikkormat Ft Serial Numbers

Hi all, I was fortunate enough to pick up my first film camera for probably 20 years in a bundle with some lenses and I am really looking forward to having a go with it. However, I am struggling a bit to work out what the exact model is and how old it may be. Apologies if there is an obvious answer, but from what I can find it has an FS serial number, however, it does have the mirror lock up and the exposure meter. Are any Nikon users out there able to tell me what the camera is? Twenty Sixty Six And Then Reflections On The Future Rare. It all seems to be working and feels really nice in the hand, it will be great to use some of my AI and AI-S lenses on a non digital camera for once.

If it is a Nikkormat FT-2. They can be recognised by a serial number beginning 'FT' and an 'N' above the meter needle.
Any tips or advice also greatly received! I'm a bit confused about the FS/FT hybrid discussion. The FT and FTN (and later Nikkormats) with meters also have a meter window on the top plate, just in front of the serial number, which is obviously missing from the FS, so it would be an odd thing to build an FT with an FS top plate and reduce its functionality by obscuring that window. The only explanation I can think of is that someone salvaged parts from an FS and used the top plate to repair an FT (or maybe an FTN). The differences between the models are quite clearly defined in the Wikipedia article or elsewhere online so perhaps you can utilise other clues to work out its provenance.

Bit of an update, firstly I put in a 675 1.4 volt battery and the meter needle sprang into life which was a pleasant surprise. I then decided to have a look under the top plate and look what I found covered up. So it must be a case of a replacement top cover being added at some point. After some further digging, this evidence along with the shutter speed being displayed in the view finder, I think points to the camera being an FTN. I have ordered the seal kit from Jon Goodman as suggested above and if all goes well after a test film I will see if I can hunt down the correct top plate. Autodesk Showcase Tutorial Pdf.
Any pointers where to look other than ebay?
The Nikomat (Nikkormat) EL is the first focal plane shutter Nikon SLR camera with aperture priority (Av) automatic exposure capability, in addition to manual exposure setting. In fact, this is one of the first cameras in the world to offer aperture priority exposure control and an electronic shutter. The camera is based on the Nikkormat mechanical body chassis, although its exterior pentaprism design is looks different from the mechanical Nikkormats (the larger prism housing design accommodates the non-flexible circuit board inside). The control interface has been changed, though, to the style of the future FE/FM series of cameras. In other words, the shutter speed and ASA (ISO) are no longer set through rings on the lens mount, but rather with dials on the top of the body.
