what makes you say that. Front end looks fine to me, pretty much the same a smy Carlton from the same era. Having said that, I have missed these things before...
the headtube alignment with the upper end of the fork appears to go in ever so slightly. it could however be a case of me 'looking for it and seeing it' rather than it actually being there.

And on the subject of carltons. This one looks like it might have had a little front on collision.
