Just wondering what the scoop is with Genuine Egli frames? The frame in question maybe for sale and it has an 'F' stamped on a plate up near the headstock. From what I've been told the plate is 'dished' and the stamping job looks rough. Is this a fake? How many different people make these things and how are they identified? I have seen frames on 'The Bay' but wonder if they are any good.
