I may be wrong but it just looks like an old pre cursa frame (I think earlier ones had Dolan on the seat tube rather than the “pre cursa” they have now), fitted with a fork with a shorter axle crown than you’d normally see?
I think you might be right. It's supposedly an old British Cycling training bike from early last decade (seller bought it from Glasgow velodrome). So that would make sense. It doesn't have the rear brake mount a FXE has either.
