... There seem to be quite a few Pen F bodies offered on EBay from Japan. ...
If it's anything like a few years ago, then they are still cheap over there. I remember a store having around 10 or more F, FT & FV bodies with and without lenses, and none of them sold.
The 38/1.8 lens is a female dog to put together again once taken apart.
I would humbly suggest that one should expect FT bodes to have non-functioning meters. Of all the ones I've handled, only the one I have now has a working meter. They are either inaccurate or dead.
Also beware of frame spacing issues! It is related to a spring(?) inside the take-up spool.
Just my 2 Yen.
Personally I love the whole Pen series. To me they are fantastic little cameras with excellent lenses.
